Will trains leave towns 663 kilometers apart at the same time and travel toward each other. one train travels 19 km h slower than the other. if they meet in 3 hours, what is the rate of each train?

Train 1 travels at speed = X

Train 2 travels at speed X - 19

Their speed of approach is:  663 kilometers / 3 hours = 221 kilometers per hour.

Now the sum of their speeds = 221 kilometers per hour

x + x-19 = 221

Simplify:

2x-19 = 221

Add 19 to both sides:

2x = 240

Divide both sides by 2:

x = 120

Train 1 travels at 120 kilometers per hour.

Train 2 travels at 101 kilometers per hour.
