Train speed = 72 km/hour

1 Km/hr = 1000/ 3600= 10/36 =5/18 metre/ second

Train speed= 72 × (5/18) m/sec

Train speed = 20 m/sec

Total distance to be covered = train length + bridge length

= 110 m + 132 m

= 242 meters

Time taken = Distance covered / Speed

Time taken by train = 242 m / 20 m/sec

Time takenby train = 12.1 seconds
