A train running at the speed of 72 km/h goes past a pole in 15 s. What is the length of the train?

150 m
200 m
300 m
350 m

Correct Answer: 300 m

Explanation:

Speed of train = Length of train / Time taken to cross the stationary object
∴ Length of train = Speed of train x Time taken to cross the stationary object
= 72 x 5 x (15/18) = 300 m
