Question 252387: A certain aircraft can fly 1280 miles with the wind in 5 hours and travel the same distance against
the wind in 8 hours. What is the speed of the wind?
A) 32 mph B) 64 mph C) 48 mph D) 80 mph Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! 5x=1280
rt=d
8y=1280
so with the wind the plane goes 256
and against the wind goes 160
256-160=96
so half of that is the wind
48 mph is the speed of the wind
(208+48)*5=1280
(208-48)*8=1280
