Train A running at 180 km/hr crosses a platform. Find time taken to cross.

1. 20 seconds
2. 24 seconds
3. 28 seconds
4. 32 seconds

Correct answer: 28 seconds

Solution

Train speed=180 km/h=50 m/s. Using the given train and platform lengths (from the full question context), time=(train+platform)/50=28 seconds.
