Find the speed of the wind?

Question

A plane has a cruising speed of 300

 miles per hour when there is no wind. At this speed, the plane flew 600

 miles with the wind in the same amount of time it flew 400

 miles against the wind. Find the speed of the wind.

Answer 1

no wind 300 mph

600 miles in same time as

against the wind going 400 miles

how fast was the wind?? 100 mph wind, very windy

d=rt

300t = 600

t=600/300 = 2 hours

(300-w)t = 400

300-w = 400/t= 400/2 = 200

w = 300-200= 100 mph

don't go fly a kite or you'll be "Gone With The Wind"
