A train 280 meters long is moving at a speed of 60 km/hr. The time taken by the train to cross a platform 220 meters long is?
Correct Answer: 30 seconds
Explanation:
∵ Speed of the train = 60 x (5/18) m/sec = 50/3 m/sec
∴ Time taken by the train to cross the platform
= Time taken by it to cover (280 + 220) m
= (500 x 3/50) sec = 30 sec
