Answer 2

Answer:

Step-by-step explanation:

Let the time after which they will meet or cross each other after be t.

Now according to the question-:

Distance traveled by train A = Distance traveled by train B

Speed of train A × Time taken by train A = Speed of train B × Time taken by train B

40×t= 80×(t-5)

on solving the equation we get t=10.

Distance after which they will meet or cross will be 10×40 = 400 miles.
