The greatest sprinters can cover the distance in under 10 seconds. It is incredibly difficult to achieve the times of the world's elite athletes. Being naturally quick is not enough to succeed. Dedicated training and specific practice are needed.

Answer 2

9.80 m/s

Step-by-step explanation

We want to find the speed in meters per seconds.

Speed is given as:

`s=\frac{\text{distance}}{\text{time}}`

So, we simply have to divide the distance by time.

Therefore, the speed is:

`\begin{gathered} s=(100)/(10.2) \\ s=9.80\text{ m/s} \end{gathered}`

That is the speed.
