1) A train running at the speed of 120 km/hr crosses a pole in 18 seconds. What is the length of the train?

2) A train 250 m long passes a bird, flying at 10 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is:

3) A train 250 m long passes a bird, flying at 10 km/hr in the opposite direction in which the train is going, in 10 seconds. The speed of the train is:

4) The length of the bridge, which a train 200 metres long and travelling at 90 km/hr can cross in 45 seconds, is:

5) Two trains running in opposite directions cross a man standing on the platform in 60 seconds and 30 seconds respectively and they cross each other in 45 seconds. The ratio of their speeds is:

6) A train passes a station platform in 72 seconds and a man standing on the platform in 30 seconds. If the speed of the train is 180 km/hr, what is the length of the platform?

7) A train 500 m long passes a man in 25 seconds. How long will it take to cross a platform 650 m long?

8) Two trains having same length are running on parallel lines in the same direction at 60 km/hr and 45 km/hr. The faster train passes the slower train in 3 minutes. The length of each train is:

9) A train 400 m long is running at a speed of 72 km/hr. In what time will it pass a bridge 100 m long?

10) Two trains are moving in opposite directions at 30 km/hr and 45 km/hr respectively. Their lengths are 1 km and 2 km respectively. The time taken by the slower train to cross the faster train (in seconds) is:
