A) 10 minutes
B) 11 minutes
C) 13 minutes
D) 13 minutes 20 sec.
Correct Answer: D
Solution :
Speed of a train \[=\frac{10}{12}\times 60\,\,kmph\] \[=50\,\,kmph\] \[=50-5=45\,\,kmph\] Now, Speed \[=50-5=45\,\,kmph\] Hence, The time taken by train to cover the same distance will be \[=\frac{10}{45}\times 60\,\,\min \] \[=13\,\,min.20sec\]You need to login to perform this action.
