Trains A and B are traveling the same direction on parallel tracks. Train A is traveling at 100 mph and train B is traveling 110 mph. Train A passes a station at 6:10 A.M. If train B passes the same station at 6:40 A.M. at what time will train B catch up with Train A?

  They are 1/2 hour apart. To catch up, they have to travel the same distance. d=100(t) d=110(t-.5) set them equal 100t=110t-55 55=10t t= 5.5 hrs. check my thinking.
