Question 705350: Train A leaves a station traveling at 40 mph. Six hours later, train B leaves the same station traveling in the same direction at 50 mph. How long does it take for train B to catch up to train A? Answer by solver91311(24713) (Show Source):
The first question you need to answer is: How far will the first train have traveled in the first 6 hours? Once you have that distance, you know how far train B has to go to catch up. The first 40 mph that train B is traveling just keeps up with train A, the only part of B's speed that allows it to catch up at all is the 10 mph difference in the two trains' speeds. So the question becomes: How long does it take to travel 240 miles at 10 miles per hour?
