Speed = Distance / Time = 150m / 25s = 6 m/s. To convert to km/h, multiply by 18/5. 6 * 18 / 5 = 108 / 5 = 21.6 km/h.

AI explanation

Using the formula for speed, the speed in meters per second is 150 m / 25 s = 6 m/s. To convert this to km/h, multiply by 18/5, which gives 6 * (18/5) = 108/5 = 21.6 km/h.
