Formula For Converting From Km/hr to m/s:
Xkm/hr = X × 5/18m/s
Therefore, Speed = 45 × 5/18m/sec
= 252m/sec
Total Distance To Be covered = (360+140)m=500m
Formula for finding
Time = Distance/Speed
∴ Requiredtime = (500×20/25sec
= 40sec.
Xkm/hr = X × 5/18m/s
Therefore, Speed = 45 × 5/18m/sec
= 252m/sec
Total Distance To Be covered = (360+140)m=500m
Formula for finding
Time = Distance/Speed
∴ Requiredtime = (500×20/25sec
= 40sec.

Calculating the time taken for the train to pass the platform:
- First, we need to convert the speed of the train from km/hr to m/s.
- Speed = 45 km/hr = 45 x (5/18) = 25/2 m/s = 12.5 m/s
- Now, the total distance the train needs to cover to pass the platform is the length of the train + length of the platform = 360 m + 140 m = 500 m
- Time taken to pass the platform = Total distance / Speed = 500 m / 12.5 m/s = 40 seconds
Therefore, the time taken for the train to pass a platform of 140 m long at a speed of 45 km/hr is 40 seconds. Hence, option 'D' is the correct answer.
