Hello, Artimid!

We have: .A pilot can travel 400 miles with the wind in the same amount of time

as 336 miles against the wind.

Find the speed of the wind if the pilot's speed in still air is 230 miles per hour.

Let = speed of the wind.

Flying with the wind, the plane's speed is: mph.

To fly 400 miles, it takes: . hours.

Against the wind, the plane's speed is: mph.

To fly 336 miles, it takes: . hours.

Since these times are equal, our equation is: .

Go for it!
