Can someone show me how to set this up rational expressions.
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 vw be velocity of wind.

400= (230+wv)time and
336=(230-wv)time

solve for wv
