Question -

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 meters is

Options:

A . 56 sec

B . 68 sec

C . 80 sec

D . 92 sec

Answer: Option C
:
C

Total distance to be covered for crossing the bridge

= length of train + length of bridge

= 150m + 850m = 1000m

Time = $\frac{D i s t a n c e}{v e l o c i t y} = \frac{1000}{45 \times \frac{5}{18}} = 80$ sec
