Show Answer

Answer:

Correct Answer: B

Solution:

Total speed of jogger and train $ =45-9=36,km/h $ (because train and jogger is in same direction) Total speeds = 36km/h $ =36\times \frac{5}{18}m/s=10,m/s $

$ \therefore $ Time taken by train to pass the jogger $ =\frac{Total,distance}{Total,speed}=\frac{(120+240)}{10}=\frac{360}{10}s=36,s $
