A train leaves a station and travels north at 60km/hr. 4 hours later, a second train leaves on a parallel track and travels north at 100km/hr. How far from the station will they meet?
Let d be the distance traveled until the trains meet. Equating the total times taken by each train, we get: [tex]\frac{d}{60}=4+\frac{d}{100}[/tex] The solution is d = 600 The answer is 600 km.
