Question 27468: Two trains, 90 miles apart, start heading toward each other at the same time. One travels twice as fast as the other. If they meet 2 hours later, at what average speed is each train traveling?
Answer by Paul(988) (Show Source): You can put this solution on YOUR website!
One train's speed = x
Other's trian's speed = 2x
TIme they meet after = 2 hours.

2(x+2x)=90
2(3x)=90
6x=90
x=15

2(15)=30.

Hence, the speed of one train is 15mph and for other its 30mph.
