Question 240800: A train leaves a station and travels north at 50km/hr. Three hours later, a second train leaves on a parallel track and travels north at 90km/hr. How far from the station will they meet? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! A train leaves a station and travels north at 50km/hr. Three hours later, a second train leaves on a parallel track and travels north at 90km/hr. How far from the station will they meet?
---------------------
In 3 hours, the 1st train is 150 km away (50*3)
The 2nd train gains on it at 40 kph (90 - 50)
To overtake it will take 3.75 hours (150/40)
3.75 hr * 90 km/hr = 337.5 km from the station
