Answer:
Average speed = 10.41 m/s
Explanation:
It is given that, in 2009, Usain Bolt set the world record for sprinting 100 m on 9 3/5 seconds.
It can be assumed to find her average speed. Speed is equal to total distance covered divided by total time taken.
![v=(d)/(t)\\\\v=(100\ m)/(9(3)/(5)\ s)\\\\=(100)/((48)/(5))\ m/s\\\\=(500)/(48)\ m/s\\\\=10.41\ m/s](https://img.qammunity.org/2021/formulas/mathematics/high-school/w2366sqw1o77pm35tv8zlr3kcmqatpeneq.png)
So, the average speed of Usain Bolt is 10.41 m/s.
