# 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

 C) 300 m

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
