A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long?

A. 40 sec

B. 42 sec

C. 45 sec

D. 48 sec

Correct Answer : A.


Formula for converting from km/hr to m/s:   X km/hr = X × 518 m/s.  Therefore, Speed = 45 x 518m/sec = 252 m/sec. Total distance to be covered = (360 + 140) m = 500 m.  Formula for finding Time = DistanceSpeed    ∴ Required time = 500 x 225 sec = 40 sec.
