Answer» Answer: Train in ORDER to CROSS the bridge it has to cross the length of the bridge and it's own length as WELL. Total length to cover = 900m+100m = 1000m Speed of the train = 72kmph * (5/18) = 20m/s Time TAKEN = Distance / Speed = 1000m/ 20m/s = 50s Time taken by the train to cross the bridge is 50s |
