Question

An airplane takes 9 hours to travel a distance of 8424 kilometers against the wind. The return trip takes 8 hours with the wind. What is the rate of the plane in still air and what is the rate of the wind?

Answer 1

Recall that: Distance = Rate * Time

=> 8424 = Rate * 9

=> Rate against the wind = 8424/9 = 936 km/h

=> Rate with the wind = 8428/8 = 1053 km
