Two trains depart at the same time from the same station and travel in opposite directions. One train travels 25 mph faster than the other train. After 2 hours the trains are 162 miles apart. Find the speed of each train.

• math -

If they travel in opposite directions, then just add their distances

distance = speed * time

2x + 2(x+25) = 162
4x + 50 = 162
4x = 112
x = 28

so, the slow train travels 28 mph
the fast train travels 53 mph
