Trains A and B are traveling in the same direction on parallel tracks. Trains A is traveling at 80 miles per hour and train B is traveling at 90 miles per hour. Train A passes a station at 10:20 P.M. If train B passes the same station at 10:23 P.M., at what time train B catch up to train A?
My answer was 12:08 am is that correct?
--------------------
In the 3 minutes, train A goes 4 miles (80mph * 1/20 hour).
Train B gains on A at 10 mph (90-80).
4 miles at 10 mph takes 0.4 hours or 24 minutes.
10:23 + 24 minutes = 10:47 PM
