The rate of a small aircraft in calm air is 125 mph. If the wind is currently blowing south at a rate 15 mph, how far north can a pilot fly the plane and return within 2 h?
Answer provided by our tutors
The distance is X
The equation is
x/(125+15) + x/(125-15) = 2
So
x = 123.2
So it can fly 123.2 miles north within 2 h
