An Olympic runner completes the 200-meter sprint in 23 seconds. What is the runner’s average speed? (Round your answer to the nearest tenth of a meter per second.)
0.9 m/s
1.2 m/s
8.7 m/s
10.1 m/s
The formula to calculate average speed is distance divided by time. In this case, the distance is 200 meters and the time taken is 23 seconds.
Average speed = 200 meters / 23 seconds = 8.7 m/s
Therefore, the runner's average speed is 8.7 m/s. So the answer is 8.7 m/s.
