A train leaves a station and travels north at 75km/h. Two hours later, a second train leaves on a parallel track traveling north at 125km/h. How far from the station will the second train overtake the first train?
**
let x=travel time for first train (hrs)
(x-2)=travel time for second train (hrs)
travel time*speed=distance (same for both trains)
75x=125(x-2)
75x=125x-250
50x=250
x=5 hrs
Distance=5*75=375 km
ans:
The second train overtake the first train 375 km from the station.
