A. 15.6 seconds
B. 16.8 seconds
C. 17.2 seconds
D. 18 seconds
Answer: Option B
Solution(By Examveda Team)
Given :Speed of running train = 60 km/hr
Length of running train = 110 metres
⇒ Length of standing train = 170 metres
⇒ Speed of the standing train = 0 km/hr
⇒ Time taken by running train to cross the standing train :
$$\eqalign{ & \Rightarrow {\text{Time}} = \frac{{\left( {100 + 170} \right){\text{ metres}}}}{{60{\text{ km/hr}}}} \cr & \Rightarrow {\text{Time }} = \frac{{280 \times 18}}{{60 \times 5}} \cr & \Rightarrow {\text{Time = 16}}{\text{.8 seconds}} \cr} $$
