Question

At noon a train leaves Washington, D.C., headed for Charleston, South Carolina, a distance of 500 mi. The train travels at a speed of 60 mph. At 1 P.M. a second train leaves Charleston headed for Washington, D.C., traveling at 50 mph. How long after the train leaves Washington, D.C. will the two trains pass each other? h

Answer 1

Below

Explanation:

The first train travels 60 miles before the second train leaves

there is 440 miles left to cover

the two trains have a closing speed of ( 60 + 50 ) = 110 mi / hr

440 mi / 110 mii/hr = 4 hrs after second train departure when the trains meet .....this would be 1 pm + 4 hrs = 5 pm ( 5 hours after the DC train leaves at noon)
