To determine the time a train takes to pass a stationary person, we apply the formula: Time = Distance / Speed.

- The train's length (distance) is 180 meters.

- The train's speed is 54 km/h. First, convert this to meters per second:

- Since 1 km/h = 5/18 m/s, 54 km/h = \(54 \times \frac{5}{18}\) m/s = 15 m/s.

- Now, calculate the time using the formula:

- Time = 180 m / 15 m/s = 12 seconds.

- The time taken is 12 seconds.

?? Correct Answer: Option 2: 12 seconds
