A plane traveled 580 miles to Anakara and back. The trip there was with the wind. It took 5 hours. The trip back was into the wind. The trip back took 10 hours. Find the speed of the plane in still air and the speed of the wind.

Answer 1

If the speed in still air is s, and the wind speed is w,

580/(s+w) = 5
580/(s-w) = 10

s=87
w=29
