Correct option is E
Let the length of the train and the bridge be 3a and 1a meters respectively
The speed of the train =

ATQ,

Required length = 3a = 150×3 = 450 meters
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).
Let the length of the train and the bridge be 3a and 1a meters respectively
The speed of the train =

ATQ,

Required length = 3a = 150×3 = 450 meters
A train crosses a platform in 20 seconds and a pillar situated on the platform in 8 seconds. If length of the platform is 264 meters, then length of the train is
Two trains start from stations A and B towards each other at speeds of 100 km/hour and 120 km/hour, respectively. At the time of their meeting, the second train has covered a distance of 280 km more than that covered by the first train. The distance between the stations A and B is
Two trains are moving in opposite directions at speeds of 140 km/h and 80 km/h. The length of one train is 340 m. The time taken by them to cross each other is 11 seconds. The length (in m) of the other train, correct to 2 decimal places, is:
Two trains having lengths of 210 m and 440 m are running at speeds of 60 km/h and 90 km/h, respectively, in the same direction. The time taken (in minutes) by the faster train, coming from behind, to completely cross the other train is:
Two trains having lengths of 410 m and 440 m are running at speeds of 60 km/h and 70 km/h, respectively, in the same direction. The time taken (in minutes) by the faster train, coming from behind, to completely cross the other train is:
Two trains having lengths of 110 m and 390 m are running at speeds of 120 km/h and 130 km/h in the same direction. The faster train, coming from behind, completely crosses the other in how many minutes?
Two trains are moving in opposite directions at speeds of 60 km/h and 70 km/h. The length of one train is 170 m. The time taken by them to cross each other is 26 seconds. The length (in m) of the other train, correct to 2 decimal places, is:
Two trains having lengths of 370 m and 330 m are running at speeds of 90 km/h and 150 km/h, respectively, in the same direction. The time taken (in minutes) by the faster train, coming from behind, to completely cross the other train is:
Train A leaves station M at 8:25 AM and reaches station N at 3:25 PM on the same day. Train B leaves station N at 10:25 AM and reaches station M at 3:25 PM on the same day. Find the time when trains A and B meet.
A 300-meter-long train can cross a 190-meter-long platform in 14 seconds. If the speed of the train increased by 20%, then find the time (in seconds) taken by the train to cross a man with a speed of 10.8 km/hr in the opposite direction.
