Question

An airplane flies against the wind from A to B in 8 hours. The same airplane returns from B to A, in the same direction as the wind, in 7 hours. Find the ratio of the speed of the airplane (in still air) to the speed of the wind.

The airplane speed in still air is v.
The wind speed is w.
The plane speed with the wind is v + w.
The plane speed against the wind is v - w.
