Question 566088: An airplane flying at a constant speed can fly 800 mile with the wind in the same amount of time it can fly 600 mile against the wind. What is the speed of the plane in still air if the wind blows at 50 mph? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! An airplane flying at a constant speed can fly 800 mile with the wind in the same amount of time it can fly 600 mile against the wind. What is the speed of the plane in still air if the wind blows at 50 mph?
------------
a = plane's airspeed
t = d/r
t = 800/(a+50) = 600/(a-50)
----
800a - 40000 = 600a + 30000
200a = 70000
a = 350 mi/hr
