<PRE><B>Question 705350</B>

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&#39;s speed that allows it to catch up at all is the 10 mph difference in the two trains&#39; speeds.  So the question becomes: How long does it take to travel 240 miles at 10 miles per hour?
