an aircraft flew 2 hours with the wind. the return trip took 3 hours against the wind. if the speed of the plane in still air is 140 miles per hour more than the speed of the wind, find the wind speed and the speed of the plane in still air

Answer 1

v = 140 + w

(140+2w)2 = (140 +w -w )3 = 420

280 + 4 w = 420 etc

Answer 2

So what is the speed of the plane and the wind speed? This didn't help very much simplify it plz.

Answer 3

I said 280 + 4 w = 420

so
4 w = 140

w = 35 mph wind speed
now go back and get v

Answer 4

what is v
