The rate of a small aircraft in calm air is 125 mph. If the wind is currently blowing south at a rate of 15 mph, how far north can a pilot fly the plane and return it within 2 h?

Answer provided by our tutors

The distance a pilot can fly the plane and return it within 2 h is x miles

The equation is

x/(125+15) + x/(125-15) = 2

So

x = 123.2

So distance a pilot can fly the plane and return it within 2 h is 123.2 miles
