Answer:

His average speed is 10.43 m/s.

Explanation:

Given that,

Distance covered by Usain bolt, d = 100 m

Time taken, t = 9.58 s

We need to find his average speed. It can be calculated using the formula of average speed as :

[tex]v=\dfrac{d}{t}[/tex]

[tex]v=\dfrac{100\ m}{9.58\ s}[/tex]

v = 10.43 m/s

So, his average speed is 10.43 m/s. Hence, this is the required solution.
