Length of train A is ‘a’ meters and speed is 144 km/hr can overtake train B whose speed is 90 km/hr in 18 seconds. If both the trains running in opposite direction, then they approximately takes ‘t’ seconds to cross each other. Find the value of ‘t’.
A train crosses a tree in 6 seconds, and it overtakes a car whose speed is 72 km/hr in 9 seconds. If the train crosses a platform whose length is ¾th of the length of the train in x seconds, then find x.
Train A, with a speed of 15 m/sec can cross a pole in 12 seconds. The ratio of the length of trains B to A is 4:3, and the speed of train B is 20% more than that of train A. Find the time taken by the trains to cross each other while running in opposite directions (in seconds).
The time it takes for a train to cross a bridge is six seconds more than that for crossing a pole. If the speed of the train is 90 km/hr and the ratio of the length of the train to the bridge is 3:1, respectively, then find the length of the train (in meters).
The ratio of the length of train A to train B is 1:3 respectively. Train A crosses a 320 meters long platform in 28.8 seconds and the speed of train A is 80 km/h. If train B crosses a 150 meters long bridge in 25 seconds, then find the speed of train B (in m/sec).
