Final answer:
The average speed of the runner is 0.075 m/s.
Step-by-step explanation:
The average speed of a runner can be calculated by dividing the distance traveled by the time taken. In this case, the distance is given as 0.005 km and the time is given as 66 seconds. To convert km to m, we multiply the distance by 1000. So, the distance becomes 5 m. Dividing the distance by the time gives us the average speed:
Speed = Distance / Time = 5 m / 66 s = 0.075 m/s
Therefore, the average speed of the runner is 0.075 m/s.
