A) 5 s
B) 6 s
C) 10 s
D) 15 s
Correct Answer: B
Solution :
Since, train and man running opposite to each other. \[\therefore \] Relative speed \[=60+6=66\,\text{km/h}\] \[=\frac{60\times 5}{18}\text{m/s}\] \[\because \] \[\text{Time=}\frac{\text{Distance}}{\text{Speed}}\] \[\therefore \] \[\text{Time=}\frac{110}{\frac{66\times 5}{18}}=\frac{110\times 18}{66\times 5}=6\,s\]You need to login to perform this action.
