C) 10.33 m/s
D) 9.25 m/s

Answer 1

Usain Bolt's average speed in the 200-meter dash was 10.34 m/s.

Step-by-step explanation:

To calculate Usain Bolt's average speed in the 200-meter dash, we need to divide the distance traveled by the time it took. The distance is 200 meters, and the time is 19.32 seconds. So, the average speed is:

Average speed = Distance / Time

Average speed = 200 meters / 19.32 seconds = 10.34 m/s

Therefore, Usain Bolt's average speed in the 200-meter dash, rounded to the nearest hundredth of a meter per second, is 10.34 m/s.
