Answer
$10.4\space m/s$
Work Step by Step
Given that,
Length of the run = 100 m
Time is taken = 9.58 s
We know, The average velocity (V)$ = \frac{Total\space displacement}{Time\space taken}$
By using the above equation, we can find the average velocity of Usain bolt
$V = \frac{100\space m}{9.58\space s}= 10.4\space m/s$
