Question 315044
A train left a station trveling 100km/h. a second train left 2 hours later and headed in the same direction at 125km/h. After many hours did the second train overtake the first train?
--------------------
In 2 hours, the 1st train went 200 km (100 x 2)
The 2nd train is gaining on the 1st train at 25 km/hr (125 - 100)
200/25 = 8 hours.
