NO! He teaches TWO things in every lesson. 1) how to solve the answer to THIS problem whatever it is, 2) how to solve ANY PROBLEM that uses this principle. Like I posted the first time someone bitched about this "he wastes my time or stretches things out". GIVE a man a fish (fine) or, TEACH A MAN TO FISH(BETTER!) My Algebra1 teacher used to warn us "don't think you're going to pass this class thinking oh 3X= 6, this is easy" cuz things are gonna get way more complex! and I ended up having to take it again in the summer! I WOULD ADVISE THIS TEACHER TO POST AN EXPLANATION AT THE TOP OF EVERY LESSON "WHY WHAT I DO MAY SEEM LIKE OVEREXPLAINING....BUT ISN'T!
Don't commit that formula to memory but understand what that formula means and why it is so. Then you don't need to memorize but you can work out this and similar formulas whenever needed. This seems to be unnecessarily complicated video to solve a simple problem. Students are likely to think that this is a very complex problem.
What messes students up the most is teachers like you. Did you even watch this before you posted it. If I didn't know how to do this I certainly would not now.
I just reasoned that since the car would travel 80 miles in one hour, I could just divide 80 by twelve (5 minute increments on clock go to 12) to find find the distance traveled. Granted this would only work for increments of 5 minutes, but it has fewer steps. Thank you very much for making these great videos! My children will be starting middle school soon so I have been trying to build up my repertoire of easy-to-understand math lessons I can use when helping them do their homework.
You explain math the same way my father the mechanical engineer did. I didn't understand you any more than I did my dad... Thank's anyway, I know you love me dad !

Greetings. Wow. This vehicle is absolutely blazing. I can't believe that this vehicle will have traveled approximately 7 miles in 5 minutes. Wow. The answer is determined as follows. We use the formula D = VT where D= distance travelled, V = velocity in MPH, and T = time taken. Now we will convert 5 minutes to hour by dividing 5 by 60 to get the the time of travel. Thereafter, we multiply the conversion rate by the velocity to get (80×5)/60 miles = 400/60 miles = 6.666666 miles, approximately 6.7 miles. This is insanely fast. That is a very far distance to travel in 5 minutes.
Math Instructors like this are the reason why most students find the subject difficult and boring. My experience teaches me that the simpler and straightforward approach yields the most results. This instructor is self-indulgent and appears to be enthralled by his knowledge.
The important thing is being aware of units and converting as needed. The rest is "plug and chug". It's similar to "you can't add gallons and pounds". You can add gallons and cups though the answer is hard to conceptualize. It's easier if the units are the same.
My 8 year old granddaughter asked me 'why don't we fall off the Earth?. This question was generated when I explained the saying 'the Sun rises in the East and sets in the West', does not mean that the Sun spins around the Earth. I said that the Earth spins like a basketball. She then asked me, why don't we fall off?
The only reason why I watched this video for about five minutes is the possibility that there might be some sort of a "catch" to a seemingly straightforward word problem that would appear on a fourth-grade test. Nope, the solution is as simple as it first appeared.
simple and fast: just divide 80 by 60, that will give distance per minute 1.3333 multiply that by 5 min will give distance of 6.66666666 round to 6.7 miles in 5 mins.
Do it in my head. At 60mph we travel 5 miles in 5 mins but at 80 mph we travel another 20mph so every 3mins we travel another mile and in 2mins another 0.66 miles. So 5 plus 1 plus 0.66 = 6.66 So how far in 5 mins at 80 mph = 6.66 miles Easy really. Best computer ever created is human brain!
I went out the back door, through the woods and over the bridge. 80 mph X 5280 (number feet per mile) = 422400 (feet per hour) ÷ 60 (min per hour)= 7040 (feet per min) X 5 (max travel time) = 35200 (ft traveled ) ÷ 5280 (feet per mile) = 6.667 or rough 6 2/3 miles.
It's not a mistake, you just have to keep track of the units. Distance = Rate × Time is absolute; therefore, 80 miles/ hr × 5 minutes is a distance. It is exactly 400 mile·minutes/hour. Now if 60 minutes = 1 hour then 1 hour/60 minutes = 1. Hence 400 mile·minutes/hour = 400 mile·minutes/hour × 1hour/60minutes = 40/6 miles = 6 2/3 miles. ◼
The amount of math "experts" in the comments is astounding. Yes there are multiple ways of solving this but people need to realize that this is a foundation builder that as you progress in math you understand the basics and it helps with higher levels of complicated problems
So the way i set up this problem was as follow please tell me if im wrong I first place 80mph equals 60 Then below the 80 i placed an x and below the 60 i placed 5 I then crossed multiplied them and i got the same answer as you. Is this set incorrect?
I just did it logically, 🚗 moving at 80/hr how many miles 5mins . Well 5mins is 1/12 of an hour, so 80/hr x 1/12 = 6.66666 or 6.67 miles. Not hard and easier than his way.
The units of speed should be writen as m/h instead of mph. Then 80m/h × 1h/60min × 5min, the h and min units will cancel out and leave behind the units of distance.
Since 5 minutes is 1/12 of an hour and the car traveled 80 miles in an hour, just divide 80 by 12. It is obvious to even the most casual 89 year old man. To be fair, I got an IQ of 130, not really close to a genius level, but close enough for this simple problem.
The way I solved it was breaking down the number of minutes into something more manageable. I took 60 minutes and divided into 10 minutes then I divided 80 by 6. Then to get it to five minutes I divided 13.333 by 2 getting 6.666 which I rounded up to 6.67.
Just about everything is defined as a ratio. Therefore, 5 mins is to 60 mins equals X is to 80 mph. X is our miles over five minutes. So. 5/60 is equal to X/80mph or, (80 X 5) / 60 = X and X equals 6.66666 miles.
In nursing school to determine doses I learned to do this: 60 minutes: 80 miles = 5 minutes : x 60 X = 400 (80 X 5) Then divide 400 by 60 and you get 6.67 My way is easier to learn. To me learning your way would be too many factors to remember. Sorry.
okay ... is this pre-algebra? Cause I was doing problems like this in ... 6th grade? 7th grade? I don't know, I was 10 or 11. x=5/60*80 x=1/12*80 x =80/12 x=20/3 x=6.6repeating miles (6 2/3)
If a car is traveling 80 MPH, how far will it travel in 5 minutes? Simple, 6 2/3 miles. How did I get that answer? 5 minutes is 1/12 of an hour. 80 miles divided by 12: 6 2/3 miles total.
Once again a teacher makes it seem like you have to be taught how to think. 80, divided by 60, times 5, equals 6.6 repeating or 6.67. Teachers make things seem long and complicated so you think you can't figure life out without them showing you how. I feel bad for kids today.
I just calculate by my self about this 6.6 miles. Before I hate to learn mathematics hours . When I adult need it but empty in it . I just use my brain to find it out . I regret the past years in the classroom
Other way to consider it is since 5 is an even multiple of 60 minutes, i.e. 1 hour, then the answer simply is 80/12 -- you're traveling at 80 mph for 1/12 an hour.
80mph is 20 mph faster than 60mph. 20mph is 1/3 of 60mph. So 80mph = 1 and a third of 60mph. At 60mph you would be traveling 1 mile every minute. At 80mph you would be traveling 1 and a third miles every minute. In 5minutes at 60mph distance travelled = 5 × 1 mile In 5minutes at 80mph distance travelled = 5 × 1 and a third miles = 5 + 5/3 miles = 6 and 2/3 miles =6.667miles
here is another problem a car is ask to drive a 2 mi stretch at an average speed of 60mph. The driver drives the first mile at 30 mph, how fast must he drive the second mile to average 60 mph
Hey Sir, That is very easy. 30+x/2 = 60 30+x/2*2 = 60*2 30+x = 120 x+30-30 = 120-30 x = 90 Therefore, he must drive at 90 miles per hour to average 60 miles per hour for 2 miles.
I went in another direction. 5 min is 1/12 of 60 min. converting 1/12 to fraction gives you .0833 and .0833 X 80 = 6.64 miles. I imagine I would receive a red check mark on my exam! lol
You have to convert time units to the same unit. Either convert hours to minutes (60) or minutes to hours (a minute is 0.0667 hours). 80 miles divided by 60 minutes equals 1.3333 miles per minute times 5 equals 6.6667 miles traveled in 5 minutes (assuming no impromptu roadside meetings with a State Trooper).
I tried to do it by saying 5 is 1/12 of an hour and then divide 80 by 12 then I realized I can't do that in my head... Then I tried to work on the mile part not the hour and said, ok, so 60mph is an easy 1 Mike/minute, how much faster is 80mph. It's 1 1/3 so 5*(1 1/3) is the answer. 5*1 = 5 plus 5*(1/3). 5*(1/3)=(6*1/3)-1/3. So 2-1/3 =1.666+5=6.6666. Wow that's crazy when I write it out like that, but it was easier than dividing 80/12... Well let's see. How many times does 12 go into 80? 6 and 8 left over... So I see the first was was actually easier, but I thought why try long division because it's usually harder.
Two way solution simplified.

Easy really. Best computer ever created is human brain!
Likewise, did it in my head.
60mph =1mi/min
20mph = 1/3 mi/min
80mph = 1mi/min + 1/3 mi/min = 1 1/3 mi/min
1 1/3 mi/min * 5 min = 5 5/3 mi = 6 2/3 mi

I used to HATE these problems. Had a VERY LAZY and unhelpful math teacher named Mr. Turner at DORSEY HS.
It's not a mistake, you just have to keep track of the units.
Distance = Rate × Time is absolute; therefore, 80 miles/ hr × 5 minutes is a distance. It is exactly 400 mile·minutes/hour. Now if 60 minutes = 1 hour then 1 hour/60 minutes = 1. Hence 400 mile·minutes/hour = 400 mile·minutes/hour × 1hour/60minutes = 40/6 miles = 6 2/3 miles. ◼

UA-cam is the largest online University! 😉👍🏿
Yes. I too am a math genius. I have been told so multiple times during online advertisements and once by my mommy.
No calculator needed:
distance = 80 miles/hour x 5/60 hour = 80 x 1/12 = 40/6 = 20/3 = 6 2/3 miles
Hmmm - 80mph - 40 miles in ½ an hour - 20 minutes in 15 minutes - 20/3≈6.67 - took longer to write out than it did to figure it out in my head.
I watched this video three times and I still don’t know how you got the answer

Distance=speed X time
80mph X 5/60

So the way i set up this problem was as follow please tell me if im wrong
I first place 80mph equals 60
Then below the 80 i placed an x and below the 60 i placed 5
I then crossed multiplied them and i got the same answer as you. Is this set incorrect?
Use 80mph ÷ .6818 to convert mph to fps. Multiply number of seconds in 5min then divide by 5280 and you get the distance.
There are twelve 5 minute segments in an hour, so divide 80/12= 6.66666666 miles
I just did it logically, 🚗 moving at 80/hr how many miles 5mins . Well 5mins is 1/12 of an hour, so 80/hr x 1/12 = 6.66666 or 6.67 miles. Not hard and easier than his way.

yes this is the easiest and quickest way and can be done in the head = 6 8/12. So shouldn't the answer 6.75 miles?
@@orweyztungchiu5819 No, it is 6 2/3 or 6.666666666666666666........
Ratio problem: 80 is to 60 as x is to 5. Now foil: 60x = 400. Now isolate the x by dividing each part by 60 = 400 divided by 60 = 6.67
The way I solved it was breaking down the number of minutes into something more manageable. I took 60 minutes and divided into 10 minutes then I divided 80 by 6. Then to get it to five minutes I divided 13.333 by 2 getting 6.666 which I rounded up to 6.67.
You made this much longer than it should have been. And to a beginner, you never showed how you solved the problem.
Just about everything is defined as a ratio. Therefore, 5 mins is to 60 mins equals X is to 80 mph. X is our miles over five minutes. So. 5/60 is equal to X/80mph or, (80 X 5) / 60 = X and X equals 6.66666 miles.
Five minutes is one twelfth of an hour. So the answer is one twelfth of eighty miles.
Going to reason it out as thus:
60 MPH = 1 MPM
20 MPH = 1/3 MPM
80 MPM = 1 and 1/3 MPM = 4/3 MPM
5* 4 = 20
20/3 = 6 and 2/3 miles
Alternatively: 80/60 * 5
4/3 * 5
20/3
5 and 2/3 miles
In nursing school to determine doses I learned to do this:
60 minutes: 80 miles = 5 minutes : x 60 X = 400 (80 X 5)
Then divide 400 by 60 and you get 6.67
My way is easier to learn. To me learning your way would be too many factors to remember. Sorry.
Minutes reduced down (5/5) =1 (60/5) =12 (80x1) / (12x1) = 6.67 Thats the way I was taught.
How many times can we fit 5min interval in 1h? So 60min/5min= 12. So in that interval car travels 1/12th of 80miles. So 80/12=6.6
How about 60 divided by 5 equals 12
then
80 divided by that 12 equals 6.67
I did it righ with out the formula..I said to myself, if 60 makes 80 ,how much 5 will make..I multiply 5x80 and then divide 400 by 60...
What??
5 minutes is 1/12th of an hour. Divide 80 by 12 and you get 6.666 recurring or 6 2/3 miles? Is this supposed to be difficult?

It is easy take 80mph ÷ by 60 minutes. = 1.333. Multiply now by 5 minutes = 6.6667 miles. So 80÷60 x5=6.6667 miles. No formulas needed, simple math.
Just do rate x time = distance
80. x. 5. =. 400
400 divide by 60 min a mile=
6.67 miles--rounded up
Other way to consider it is since 5 is an even multiple of 60 minutes, i.e. 1 hour, then the answer simply is 80/12 -- you're traveling at 80 mph for 1/12 an hour.
You all are so funny
80mph is 20 mph faster than 60mph.
20mph is 1/3 of 60mph.
So 80mph = 1 and a third of 60mph.
At 60mph you would be traveling 1 mile every minute.
At 80mph you would be traveling 1 and a third miles every minute.
In 5minutes at 60mph distance travelled = 5 × 1 mile
In 5minutes at 80mph distance travelled = 5 × 1 and a third miles
= 5 + 5/3 miles
= 6 and 2/3 miles
=6.667miles
(80mi/60mins)x5mins ~ 6.67mi
Some cars have different size wheel the sensor goes in laps. Its 7m wen i did my calculations for the same car but different sizes wheel
It is good to remember
60 mph is a mile a minute. 80 mph is a mile a minute plus 20/60 of a mile a minute. Now just add the two.
Simple division. 6&2/3 miles.
here is another problem a car is ask to drive a 2 mi stretch at an average speed of 60mph. The driver drives the first mile at 30 mph, how fast must he drive the second mile to average 60 mph
Hey Sir,
That is very easy.
30+x/2 = 60
30+x/2*2 = 60*2
30+x = 120
x+30-30 = 120-30
x = 90
Therefore, he must drive at 90 miles per hour to average 60 miles per hour for 2 miles.
60 min--80miles. 1min-80/60=4/3 mile. 5 min-4/3x5=20/3=6 2/3 miles. Ans
5 minutes is obviously 1/12 of an hour, so your answer is 1/12 of 80 miles
(80 miles/hour ) ( 1 hour/60 minutes ) (5 minutes) = 80 miles x 1 x 5 / 60 ~= 6.67 miles
*notice of the unit cancellation
I’m not mad at you, I’m pushing yiur brain
Let me guess the i
What on Earth is all this stuff?
It's simple maths ! Takes a few seconds.
80 miles in 60 mins is
1.33 miles in 1 minute
6.67 miles in 5 minutes
Why do you make this so complex?
I went in another direction. 5 min is 1/12 of 60 min. converting 1/12 to fraction gives you .0833 and .0833 X 80 = 6.64 miles. I imagine I would receive a red check mark on my exam! lol
Talk about overthinking the equation
80 = 10 6 minute pay periods or
8 mph per 6 minutes or 8 ÷ 6 = 1.333
1.33 × 5 =6.65
D=VT. 80m/hr X 5minutes. D=80M÷60minutes X5minutes D=400m/60. D=6.67miles
Around 6.5 miles off the top of my head. 20 miles in 15 min...so a third of 20.
What percentage of 60 is 5? 12. 5/60 reduced down to 1/12 x 80 = 6.67 miles. Much simpler
I'm going to find out right now 🤔 🚗💨
Conversion is comfusing the way u explained
If a car travels 80 miles in 1 hour then it travels 80 miles in 60 minutes. 5 divided by 60 = 0.0833 times 80 = 6-2/3rds miles.
You have to convert time units to the same unit. Either convert hours to minutes (60) or minutes to hours (a minute is 0.0667 hours). 80 miles divided by 60 minutes equals 1.3333 miles per minute times 5 equals 6.6667 miles traveled in 5 minutes (assuming no impromptu roadside meetings with a State Trooper).
I agree
80/60*5=Correct answer.
I tried to do it by saying 5 is 1/12 of an hour and then divide 80 by 12 then I realized I can't do that in my head...
Then I tried to work on the mile part not the hour and said, ok, so 60mph is an easy 1 Mike/minute, how much faster is 80mph. It's 1 1/3 so 5*(1 1/3) is the answer.
5*1 = 5 plus 5*(1/3). 5*(1/3)=(6*1/3)-1/3. So 2-1/3 =1.666+5=6.6666.
Wow that's crazy when I write it out like that, but it was easier than dividing 80/12... Well let's see. How many times does 12 go into 80? 6 and 8 left over... So I see the first was was actually easier, but I thought why try long division because it's usually harder.
