Question

Flying against the wind, an airplane travels 3760 kilometers is 4 hours. Flying with the wind, the same plane travels 11,520 kilometers in 8 hours. What is the rate of the plane in still air and what is the rate of the wind?

Rate of the plane in still air: _km/h
Rate of the wind: _km/h
​

Answer 1

Rate of the plane in still air: 940km/h

Rate of the wind: 1440km/h

Explanation:

We want to find the rates of travel in km/h, so we will put kilometers over hours.

Rate of plane against wind: 3760km/4hrs

3760/4 = 940

The rate of the plane against the wind is 940km/h

Rate of plane with wind: 11,520km/8hrs

11,520/8 = 1440

The rate of the plane with the wind is 1440km/h
