The speed of train A is 10 mph slower than the speed of train B. Train A travels 230 miles in the same time it takes train B to travel 280 miles. Find the speed of each train.

The speed of train A is ?mph

The speed of train B is ?mph

Solution:

The speed of train A is x mph

The speed of train B is x+10 mph

230/280 = x/(x+10)

x = 46

So

The speed of train A is 46 mph

The speed of train B is 56 mph
