Two planes left at the same time from two airports which are 4,500 miles apart and flew toward each other. In 5 hours, they passed each other. The rate of the fast plane was twice the rate of the slow plane. Find the rate of each plane.
-----------------
Their combined rates = 4500 miles/5 hrs = 900 mph
----------------
EQUATION:
Their rates are 2x and x
2x+x = 900
3x = 900
x = 300 mph (rate of slow plane)
2x = 600 mph (rate of fast plane)
