Question

The distance between two stations a and b is 300 km. a train leaves station a at the speed of 30 kmph. at the same time another train departs from station b at the speed of 45 kmph. what will be the distance of the point where both the trains meet from the point a?

Answer 1

Both trains will be meeting at 120 km from Station A and 180 km from Station B as the train which leaves Station A at the speed of 30 kmph after 4 hours will cover a distance of 120 km and the train which leaves Station B at the speed of 45 kmph after 4 hours will cover a distance of 180 km.As the total distance between Station A and B is 300 km ,the total distance covered by Train leaving Station A will cover 120 km and the Train leaving Station B will cover 180 km.
120 km +180 km = 300 km .
