Step-by-step explanation:
Speed of the Train = 45 km/hr = 12.5 m/s.
Time taken to cross a single pole = 18 seconds.
Therefore, Length of the Train = 12.5 × 18 = 225 m.
Now, for Platform, Total distance to be covered = length of the train + length of the platform
= 225 + 125
= 350 m.
Now, Time taken to cross the Platform = Total length/Speed of the train
= 350/12.5
= 28 seconds.
Hence, the time taken by the train to cross the Platform is 28 seconds.
Hope it helps.
