Question

If a plane can travel 450 miles per hour with the wind and 410 miles per hour against the wind, find the speed of the plane without a wind and speed of the wind?

Answer 1

The speed of the plane through the air is 430 mph, and you described a day when the wind was blowing at 20 mph.

Answer 2

Assuming that Rp = speed of the plane and Rw = speed of the wind

450 = Rp + Rw

410 = Rp - Rw

(add both equations)

860 = 2Rp

Rp = 430

Hope this helps
