Set up the equation you would use to solve the problem. Do not actually solve the equation. A plane flies 390 miles with the wind and 325 miles against the wind in the same length of time. If the speed of the wind is 10 miles per hour, fine the speed of the plane in still air. (Let x = speed of the plane.)

A. 390/x+20 = 395/x

B. 390/x+10 = 325/x-10

C. 390/x = 325/x-20

D. 390/x-10 = 325/x+10
