Question

Quizplus · Accepted Answer

The average speed is the total distance divided by the total time, which is 2 km / (10 * 60) s = 1/300 km/s or approximately 0.00333 km/s. However, since none of the options match this, the closest interpretation is that the speed is 12 km/h (not km/s), which is not directly provided. The average velocity is 0 because he ends up at the starting point, resulting in no net displacement.
