Train A and B are traveling in the same direction on parallel tracks. Train A is traveling at 80 miles per hour and train b is traveling at 96 miles per hour. Train A passes a station at 1:10 a.m. if train B passes the same station at 1:25 a.m., at what time will train b catch up to train A.

Best ResponseYou've already chosen the best response.0I love mechanics. Find out how far the first train has travelled by 1:25. The second train has to 'catch up' this distance, and it is catching up at a speed of 9680 = 16mph.

Best ResponseYou've already chosen the best response.0Between 1:10 and 1:25, 15 minutes passes  1/4 hours distance = speed x time > train A travels 80 x (1/4) = 20miles in this time. From 1:25, train B catches up at 96  80 = 16 mph. It needs to catch up 20 miles at 16mph relative speed, so the time is (20/16) hours after 1:25
