With a certain tail wind, a airplane reached its destination 630 miles away in 1 1/2 hours. Flying back against the same wind, the plane took 15 minutes longer to make the trip. Find the wind speed and the plane's air speed.
---------------
630/1.5 = 420 mph
630/1.75 = 360 mph
The airspeed is the average = (420+360)/2 = 390 mph
The wind speed is the difference, = 30 mph
