I just don't understand how to start building equations, where to start. Plz Read the question below

-----------------------------------------------------------------------------

An aircraft flies 1062 miles with the wind at its tail. In the same

amount of time, a similar aircraft flies against the wind 738 miles. If the air speed

of each plane is 200 miles per hour, what is the speed of the wind? (Hint: Time

equals the distance divided by the speed.)

-----------------------------------------------------------------------------

The wind is in favor of the first air craft i.e. its pushing it and that's why it is able to cover more distance unlike the other air craft. so i can say that if x is the wind speed then for the first aircraft it is directly proportional so 200x, means its boosting the plane speed and for the other plane its 200/x as it is opposing it.

After this i go blank, now what. so plz help.

Answer is 36miles/hours
