Rate*Time=Distance
R%5Bw%5D%2AT=D%5Bw%5D Westbound plane
R%5Be%5D%2AT=D%5Be%5D Eastbound plane
D%5Bw%5D%2BD%5Be%5D=2250 Total distance
R%5Bw%5D%2AT%2BR%5Be%5D%2AT=2250 Substitute
R%5Bw%5D%2A3%2BR%5Be%5D%2A3=2250
R%5Be%5D=R%5Bw%5D-150 Eastbound plane travels 150 mph slower.
R%5Bw%5D%2A3%2B%28R%5Bw%5D-150%29%2A3=2250
R%5Bw%5D%2B%28R%5Bw%5D-150%29=2250%2F3Divide both side by 3.
2R%5Bw%5D-150=750
2R%5Bw%5D=900
highlight%28R%5Bw%5D=450%29
R%5Be%5D=R%5Bw%5D-150
R%5Be%5D=450-150
highlight%28R%5Be%5D=300%29
Westbound plane travels at 450 mph, eastbound plane at 300 mph.
