Two trains continuously travel between Washington DC and Baltimore, which is 500 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 third time?
This is a similar question posted at https://www.beatthegmat.com/trains-t110287.html#469513
but with a different flavour. The first one was relatively easy ? but how do you solve this one ?.
Note : I donot know the answer. The only way i would do this is to manually test the distances and speeds for each section. And that is horrible. Can anyone tell me the way, or if there is no other way and such a problem will not come on gmat.
