Answer:
hiii
your answer is here !
Step-by-step explanation:
=> Speed = 100 km/hr = 100 x 5/18 = 250/9 m/sec.
=> Time taken to cross = 30 seconds.
=> Therefore,
=> distance traveled = 250/9 x 30 = 2500/3 m.
=> Distance = Length of the train + length of the bridge
=> 2500/3 = Length of the train + 500 Length of the train = 1000/3 m
=> follow me !

Step-by-step explanation:
Given = Speed = 100 km / hr × 5/18
= 250/9 m/sec
Time = 30 sec
So distance = speed × time
250/9 × 30 = 2500/3
Dis = Length of the train + Length of bridge
Length of the train + 500 Length of the train = 1000/3 m
