Town A and B are 420 miles apart. if a train leaves for B at 60 mph, how many hours will it take to meet another train going from B at 45 mph?

Answer 1

To find out how many hours it will take for the trains to meet, we need to determine the distance that the two trains will cover together.

If train A is traveling at 60 mph and train B is traveling at 45 mph, the combined speed of the two trains is 60 mph + 45 mph = 105 mph.

Since they are 420 miles apart, it will take them 420 miles ÷ 105 mph = <<420/105=4>>4 hours to meet.

Therefore, it will take 4 hours for the two trains to meet.
