Given, Length of train = 110 meter
Speed of train =72 km/hr
Length of bridge =132 metre

—> Converting Speed from km/hr into m/sec
=>Speed of train = 72 * (5/18) m/sec
= 4 * 5
= 20 m/sec

Formula:-Time taken by train to cross the bridge = (Length of the train + Length of the bridge) /Speed of train
= (110 + 132) / 20
= 242/ 20
= 12.1 sec

Thus,Time taken by train to cross the bridge =12.1 seconds
