8 meters per seconds simply implies covering a distance of 8 meters in 1 seconds. The situation describes speed. Therefore,


\begin{gathered} \text{speed}=\frac{dis\tan ce}{\text{time}} \\ \text{speed}=(8)/(1)=8ms^(-1) \end{gathered}

We will look for similar one in the options


\text{speed}=(80)/(10)=(8)/(1)=8ms^(-1)

The answer is 80 meters in 10 seconds.
