- The train's length is 900 meters.

- The platform's length is also 900 meters.

- To clear the platform, the train must travel a total distance of 1800 meters (900 m train + 900 m platform).

- Train's speed: 108 km/h. Converting this to meters per second: \( 108 \times \frac{1000}{3600} = 30 \) m/s.

- Time taken to cover 1800 meters at 30 m/s: \( \frac{1800}{30} = 60 \) seconds.

- Options given:

1. 60 seconds

2. 45 seconds

3. 30 seconds

4. 18 seconds

The correct answer is option 1: 60 seconds.
