Impressive. As a baby Boomer I grew up with side rules ( hatch, we went to the moon using slide rules…). This is the slide rule for sky travel!
Well, the FAA was looking for an answer of 43 minutes, but that’s not factually accurate. This is because with the time of climb, there is an amount of distance that is also utilized. This is found in the POH time distance fuel to climb chart. So the distance between the two airports become less in a sense because you have covered distance within the three minutes from the departure airport and the time in cruise with the ground speed of 80 kts which is going to be less than the total. Probably in this example very minuscule, but you would be at 80 kn for something like 37 or 38 miles not the full 40. so, the actual calculation should be the distance to climb, according to the POH at the recommended airspeed, the distance in cruise at the figure speed of 80 kn then, unless you can maintain that airspeed descending to pattern altitude, you have to subtract that distance from the cruise portion and recalculate the time. So in short, you have to add time to climb, time in Cruise and time to descend. Then a ballpark figure of three minutes in the pattern. Sounds complex, but that is how you calculate a true ETE. But the time required to fly 40 miles on the test is close enough for government work.
