A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?
Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is:
Let the length of each train be x metres.
Then, distance covered = 2x metres.
Relative speed = (46 - 36) km/hr
2x = 100
x = 50.
A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long?
Total distance to be covered = (360 + 140) m = 500 m.
Two trains are moving in opposite directions @ 60 km/hr and 90 km/hr. Their lengths are 1.10 km and 0.9 km respectively. The time taken by the slower train to cross the faster train in seconds is:
Relative speed = (60+ 90) km/hr
Distance covered = (1.10 + 0.9) km = 2 km = 2000 m.
A jogger running at 9 kmph alongside a railway track in 240 metres ahead of the engine of a 120 metres long train running at 45 kmph in the same direction. In how much time will the train pass the jogger?
Speed of train relative to jogger = (45 - 9) km/hr = 36 km/hr.
= 10 m/sec.
Distance to be covered = (240 + 120) m = 360 m.
