Explanation:

Let’s solve the problem step-by-step:

- Initial speed (u) = 0 (train starts from rest)

- Final speed (v) = 108 km/h = 30 m/s (since 108 × 1000 / 3600 = 30)

- Time (t) = 5 min = 300 seconds

- Using the formula: v = u + at

30 = 0 + a × 300

? a = 30 / 300 = 0.1 m/s²

- Distance covered (s) = ut + (1/2)at²

s = 0 + 0.5 × 0.1 × (300)²

s = 0.05 × 90000 = 4500 m

- Option 1: 9000 m – Too high (would mean almost double the acceleration)

- Option 2: 4500 m – Correct answer

- Option 3: 355 m – Too low (not possible in 5 minutes)

- Option 4: 108 m – Much too low (would be done in a few seconds at this speed)
