A) 50 s
B) 60 s
C) 64 s
D) 54 s
Correct Answer: D
Solution :
\[\because \] Speed of train = 50 km/h \[=50\times \frac{5}{18}\]m/s \[=\frac{125}{9}\,\]m/s \[\therefore \] Required time \[=\,\frac{\text{Distance}\,\text{covered}}{\text{Speed}}\] \[=\frac{(150+600)}{125}=\frac{750\times 9}{125}=54\,\,s\]You need to login to perform this action.
