On the school playground, the student ran a 60 m track in 9.5 s. What is the average speed of his run?

Correct answer:

v =  6.3158 m/s

Step-by-step explanation:

$$\begin{gathered} s=60\text{ m } \\ t=9.5\text{ s } \\ v=s\mathrm{/}t=60\mathrm{/}9.5={\displaystyle \frac{120}{19}}=6.3158\text{ m/s} \end{gathered}$$
