My logic was...
total distance between cities is 225 miles. Train A will make that trip in 4.5 hours (225/50). Train B will make that trip in 3.75 hours (225/60). If train B leaves 30 minutes later (or .5 hours) and the difference in travel times is .75 hours, then they'll meet somewhere close to the middle.
If you want the exact answer, yes the math can be worked out for a precise time and distance. but I, too, thought it was probably a trick question about a city between those two places (like Hartford, CT) which someone who travels that trip would know.
