A `150 m` long train is moving with a uniform velocity of `45 km//h`. The time taken by the train to cross a bridge of length `850` metres is.

A

56 sec

B

68 sec

C

80 sec

D

92 sec

Text Solution

Verified by Experts

The correct Answer is:
C
Total distance = 150 + 850 = 1000m
Time ` = (1000)/(45 xx 5/18) = 80sec`
