A train running at 60 km per hour crosses a pole in 18 seconds. What is the length of the train?

Explanation:
Speed of the train is 60 km per hour. Convert it into metres per second: 60 x 5 divided by 18 = 16.67 m per second. Time taken to cross a pole is 18 seconds. Length of train = speed x time = 16.67 x 18 = 300 metres. Train questions are common in quantitative aptitude. Candidates should remember that while crossing a pole, distance covered is equal to the length of the train.
