a + w = 3240/4.5 = 720 mph
a  w = 3240/5 = 648 mph
2a = 1368
a = 684 mph
w = 720684 = 36 mph
Ans:
Aircraft Airspeed = 684 mph
Wind speed = 36 mph

From Como: Let speed of plane in still air = x mph

An airplane travels 3240 miles in 4.5 hours with the aid of a tail wind.
It takes 5 hours for the return trip, flying against the same wind.
Find the speed of the airplane in the still wind, and the speed of the wind.
3240/(p + w) = 4.5
3240/(p  w) = 5
4.5(p + w) = 5(p  w)
0.5p = 9.5w
p = 19w
Airplane speed: miles per hour
Wind speed: miles per hour
