A pilot flew a 400-mile flight in 2.5 hours flying into the wind. Flying the same rate and with the same wind speed, the return trip took only 2 hours, with a tailwind.

Question

What was the speed of the wind?

Answer 1

since distance=speed*time,

(p-w)(2.5) = 400
(p+w)(2) = 400

Now just solve for w, the wind speed.

Answer 2

40

Answer 3

the correct answer is 20 miles per hour. I just answered 40 and it counted it wrong and said it was 20. Good luck

Answer 4

The correct answer is 20.
