Flying with the wind, a plane traveled 390 miles in 3 hours. Flying against the wind, the plane traveled the same distance in 5 hours. Find the rate of the plane in calm air and the rate of the wind. rate of plane ? mph
rate of wind ? mph

• algebra -

If the speed of the plane and the wind are p and w, then since distance = speed * time,

3(s+w) = 390
5(s-w) = 390

s = 104
w = 26
