Two trains continuously travel between Washington DC

    Two trains continuously travel between Washington DC and Baltimore, which is 120 miles away. They start simultaneously, train A at Washington and train B at Baltimore, and run at 30 and 90 mph respectively. The station turnaround times are negligible. What is the distance between the point where the trains meet for the first time and the point where they meet for the second time?

    A) 0
    B) 30 miles
    C) 60 miles
    D) 90 miles
    E) 120 miles

    B is the OA.

    Can anybody do a graph where I can see the two points where the meet each other? It would be helpful.
