B Correct answer
Explanation

Speed = Distance / Time = 180m / 6s = 30 m/s. Convert to km/hr: 30 * (18/5) = 6 * 18 = 108 km/hr.

AI explanation

Using the speed formula, the speed of the train is 180 m divided by 6 seconds, giving 30 m/s. To convert meters per second to kilometers per hour, multiply by the factor 18/5. Thus, 30 multiplied by 18/5 equals 108 km/hr. The result is 108 km/hr.
