Answer:

Let the speed of train B be x mph. Then, the speed of train A is (x+30) mph, since it is traveling 30 mph faster.

We can use the formula:

time = distance / speed

to set up two equations, one for each train:

time taken by train A = 240 / (x+30)

time taken by train B = 150 / x

Since the two trains take the same amount of time to travel their respective distances, we can set these two equations equal to each other:

240 / (x+30) = 150 / x

Cross-multiplying, we get:

240x = 150(x+30)

240x = 150x + 4500

90x = 4500

x = 50

So, the speed of train B is 50 mph, and the speed of train A is 50+30 = 80 mph.

Therefore, train A was traveling at 80 miles per hour and train B was traveling at 50 miles per hour.
