Asked by Christy

Trains A and B are traveling in the same direction on parallel tracks. Train A is traveling at 40mph, B is traveling at 44 mph. Train A passes a station at 820am, train B passes the same station at 850. At what time will train B catch up to train A.
My estimate is 924am

Your estimate is way off. How did you get it?

At 8:50 AM, Train A is ahead by (40 miles/h)(1/2 h) = 20 miles. The distance netween trains gets reduced at a rate of 44-40 = 4 mph. The gap between trains becomes zero in 20/4 = 5 hours.

Add 5 hours to 8:50 AM.
