A train of length 180 m, running by 72 km/h to cross the another train B which is running in the opposite direction to speed of 108 km/h and length is 120 m, in how much time?


A) 23 s

B) 12 s

C) 6 s

D) 30 s

Correct Answer:
C) 6 s

Description for Correct answer:

Required time = \( \Large \frac{Distance \ covered \  by \  train}{Relative \  speed \  of \  train} \)

\( \Large \frac{180+120}{ \left(72+108\right) \times \frac{5}{18} } \)

\( \Large \frac{300 \times 18}{180 \times 5} \) = 6 s.
