at maximum speed an airplane travels 1680 miles against the wind in 5 hours . Flying with the wind the plane can travel the same distance in 4 hours
Let x be the maxium speed of the plane and y be the speed of the wind. What is the speed of the plane with no wind?
---------------
With wind DATA:
distance = 1680 mi ; 4 hrs ; rate = 1680/4 = 420 mph
---------------------------------------------------------------
Against wind DATA:
distance = 1680 ; time = 5 hrs ; rated = 1680/5 = 336 mph
------------
Equations:
x+y = 420
x-y = 336
-----------------
Add and solve for "x":
2x = 756
x = 378 mph (speed of the plane in still air)
