Answer:
250 meters
Step-by-step explanation:
speed : 54 km/hr
Time : 30 seconds
length of train: 200 meters
Above is the speed for 1 second =
54km/ 3600seconds
Distance traveled in 1 second = 0.015km
Distance traveled in 30 seconds = 0.45km
Now length of train is 200 meters but whole train from starting to ending traveled 0.45 km in 30 seconds among which 200 meters is the trains own length thus
length of bridge = 450 meters - 200meters = 250 meters
