You don't have quite enough information to solve this question. You need to know; 1) are the trains going in opposite directions? If not, then they may never meet 2) did the trains leave from the same station? 3) did the trains leave at the same time? 4) did the trains leave travelling at their stated speeds? Love to help, but, as stated, can't
10:00 is the answer
At 2:45, Train-A has a 1/2-hour lead on Train-B = 1/2 of the speed of Train-A = 5 miles.Train-B overtakes Train-A at the rate of (50 - 40) = 10 miles per hour.It takes Train-B (5/10) = 1/2 hour to make up the deficit.Train-B catches up to Train-A at 3:15 AM.
it would take 36 minutes.
i think it would take 1 hour
Perhaps you mean catch-22. This is a phrase derived from a novel of that name: http://en.wikipedia.org/wiki/Catch-22
make train a go 88
10:00 is the answer
8:49
Train B will catch up to train A at 2:47am

1 day (24 hrs.)
8:08am when train b reaches the station the distance from train a is 12 miles. the relative speed between the trains is 20mph passing 12 miles in 20mph takes 0.6 hours which is 36 minutes. 36 minutes after 7:32 is 8:08
Hauptbahnhof (Main Station)
Train B Will Catch Up To Train A In 11 Hours.
Hopefully never, because they are obviously on a collision course. I hope they're cargo trains and not passenger trains.
About 40 miles but if you're in London, catch the Eurostar train from St Pancras and it passes through Ebbsfleet.
