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
iogann1982 [59]

Answer:

Step-by-step 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
