Question

A plane flies 1225 miles with the wind in the same time it can fly 1100 miles into the wind. The speed of the plane in still air is 575 miles per hour. Which equation would you use to find the speed of the wind?​

Answer 1

Explanation:

v=d/t, t=d/v, since t=t

1225/(v+w)=1100/(v-w)

1225v-1225w=1100v+1100w

2325w=125v

w=125v/2325, given v=575

w=125(575)/2325

w=30.91 mph
