You can put this solution on YOUR website! An airplane, traveling with a tail wind, travels 1000 miles in 2 hours. The return trip, against the wind, takes 2.5 hours. Find the speed of the wind(assume that both rates are constant)
-------------
w = wind speed
r = plane's airspeed
---------
1000 = 2(r+w)
1000 = 2.5(r-w)
r + w = 500
r - w = 400
------------
2r = 900
r = 450 mph
w = 50 mph
