Question

Train A, 25ft long, leaves the station going 50m/hr going north. Train B, 20ft long, leaves the station going 55m/hr going south. They both leave at 9 am. At what time will they meet?

Answer 1

The meeting time for the trains cannot be calculated without knowing the initial distance between the two trains departing from the station at 9 am, as the relative speed alone is not sufficient to determine the time at which they will meet.

Step-by-step explanation:

To find the meeting time, we need to consider the relative speeds of the trains and their starting times. Train A is moving north at a speed of 50 mph, and Train B is moving south at a speed of 55 mph. Since they are moving in opposite directions, their relative speed is the sum of their individual speeds, which is 50 mph + 55 mph = 105 mph. They both leave the station at 9 am. To find the time at which they will meet, we need to divide the distance between them by their relative speed. However, since no initial distance apart is provided, we cannot calculate an exact meeting time.
