D Correct answer
Explanation

Speed = distance / time. Distance = 60 km = 60000 m. Time = 10 min = 600 s. Speed = 60000 / 600 = 100 m/s.

AI explanation

To find the speed in SI units, first convert the given values to meters and seconds. The distance of 60 km is 60,000 meters and the time of 10 minutes is 600 seconds. Using the formula speed equals distance divided by time, 60,000 meters divided by 600 seconds gives a speed of 100 m/s.
