Answer 7

(s - w) = plane speed against the wind
(s + w) = plane speed with the wind

5(s - w) = 1170 ---> s - w = 1170/5
4.5(s + w) = 1170 --> s + w = 1170/4.5

s - w = 234
s + w = 260
-----------add
2s = 494
s = 247 ===> plane speed in still air

247 - w = 234
247 - 234 = w
13 = w ==> wind speed is 13 mph

check..
5(s - w) = 1170
5(247 - 13) = 1170
5(234) = 1170
1170 = 1170 (correct)

oh crap...I think I just found the answer...
plane speed in still air = 247 mph
wind speed = 13 mph
