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

A) 150 m

B) 200 m

C) 300 m

D) 350 m

Correct Answer:
C) 300 m

Description for Correct answer:

Speed of train

= \( \Large \frac{ Length \  of \  train }{ Time \  taken \  to \  cross \  the \  stationary \  object } \)

Therefore, Length of train = Speed of train X Time taken to cross the stationary object

= \( \Large \frac{72 \times 5 \times 15}{18} \) = 300 m
