A train travels 75 km per hour .How much time will it take to cross a bridge of length 500 m if the length of the train is 50 m?

1
Length of the train is 50m or 0.050km
Length of the bridge is 500m or 0.500km
Total length the has to cover is 0.050km + 0.500km = 0.550km
Speed of the train = 75km/h
Therefore, time taken by the train = 0.550km / 75km/hr = 11/1500 hr or 26.4sec
