Ok my students sent this to me with some other things but I really don't want to feel dumb. For some reason I'm thinking I've seen this before and it's a riddle that has no answer but I need help

And no, I obviously do not teach math (haha)
Train A, traveling 50 miles per hour, leaves New York at 12:00pm heading
toward Boston, 225 miles away. Train B, traveling 60 mph, leaves Boston
at 12:30pm, heading toward New York. When do the two trains meet?
