The speed of train A is 12 mph slower than the speed of train B. Train A travels 210 miles in the same time it takes train B to travel 270 miles. Find the speed of each train.

the speed of A train is?

the speed of B train is?

Let the speed of train B be x, then speed of A will be x-12.

Time taken by A = 230 / (x-12)

Time taken by B = 290/x

Given that the time taken by train A = Train B

Then, 230 / (x-12) = 290/x

23x=29x-349

6x=349

x=58

Therefore, the speed of the train A is (x-12, 58-12=46) 46 and Train b is 58

Have a wonderful day : D
