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.

math/physics 
drwls,
Let the wind speed be v.
400/(230 +v) = 336/(230v) is the flight time in either direction.
Solve for v. It will be in mph
