Question
Two trains start from stations A and B towards each
other at the same time. The distance between A and B is 360 km. One train runs at 40 km/h and the other at 50 km/h. After how many hours will they meet and how far from station A will they meet?Solution
Relative speed when moving towards each other = 40 + 50 = 90 km/h Time to meet = Distance / Relative speed = 360 / 90 = 4 hours Distance from A = speed of train from A Ă time = 40 Ă 4 = 160 km Answer: They meet after 4 hours, at a point 160 km from station A.
