Question
Two trains of equal lengths are running on parallel tracks in the same direction at 46 km/hr and 36 km/hr respectively. The faster train passes the slower train in 36 seconds. What is the length of each train?
Solution
ATQ, Relative Speed = 10 km/hr = 10 * 5/18 = 25/9 m/s. Distance (2L) = Speed x Time 2L = (25/9) x 36 = 100. L = 50m.
