Step-by-step explanation:
Let, length of bridge = x m
Length of train = 130 m
Speed of train = 45 km/hr = 45000/3600 meters/sec = 12.5 m/s
In order to completely cross the bridge, distance traveled by train = (x+130) m
Time taken to cross = 30 s
Distance traveled in 30 sec = 12.5 X 30 = 375 m = x + 130
Length of bridge, x = 375 - 130 = 245 m
