Question 647172: A train leaves NYC for Washington DC traveling at 90 mph. At the SAME TIME, a train leaves Washington DC for NYC traveling at 95 mph. If NYC and Washington DC are 462.5 miles apart, how long will it take before the two trains meet?
*I do believe that "how long will it take" refers to the distance in miles since the problem doesn't involve time.
Will the question have two answers since there are two starting points?
Thank you for your help :D
