A railway train is 100 m long and running at the speed of 30 km per hour. In what time will it pass a bridge 80 m. long?


A) 12 sec

B) 18 sec

C) \( \Large 21\frac{3}{5} \) sec

D) 24 sec

Correct Answer:
C) \( \Large 21\frac{3}{5} \) sec

Description for Correct answer:

t = \( \Large \frac{100+80}{30 \times \frac{5}{18}} \)

\( \Large \frac{180 \times 18}{30 \times 5} = 21\frac{3}{5} \)sec.
