Question

A train traveling 50 mph left a station 30 minutes before a second train running at 55 mph. How soon did the second train overtake the first? If 50x represents the distance the slower train travels, then the faster train travels

Answer 1

First you need to find the distance traveled by the first train in the 30 minutes before the second train left. Call this distance 50x miles, where x = 1/2 hour. This distance is therefore 25 miles. Now the next step is to find how long the second train takes to travel 25 miles at the closing speed of 55 - 50 = 5 mph.
