You can put this solution on YOUR website! At maximum speed,an airplane travels 2400 miles against the wind in six hours.
distance = 2400 ; time = 6 hrs. ; rate = 2400/6 = 400 mph
---------------------------
Flying with the wind, the plane can travel the same distance in 5 hours.
distance = 2400 ; time = 5 hrs ; rate = d/t = 480 mph
---------------------------
What is the speed of the plane with no wind?
Equations:
p+w = 480 mph
p-w = 400 mph
-----
2p = 880 mph
p = 440 mph (speed of the plane with no wind)
