Two trains, 390 miles apart, start traveling toward each other at the same time and meet 3 hours later. If the speed of one train is 30 mph faster than the other, find the speed of each.
**
let x=speed of slower train
x+30 =speed of faster train
distance=travel time*speed
..
3x+3(x+30)=390
3x+3x+90=390
6x+300
x=50
x+30=80
speed of slower train=50 mph
speed of faster train=80 mph
