Question

Two planes took off from a Chicago airport flying in opposite directions. One plane traveled 30mph faster than the other. They were 1500 miles apart after 2hrs. How fast was each flying

Answer 1

If one's speed = x, then the other's speed = x+30.

2x + 2(x+30) = 1500

Solve for x and x+30.

Answer 2

One is traveling 360 mph and the other is traveling 390 mph.
