Question

A car covers a distance of$800km$ in $10hours$. What distance would it cover in $8hours$?

Answer 1

Given that

A car covers a distance of$800km$ in $10hours$

Let the distance it will cover $xkm$ in $8hours$

we have

$$\begin{gathered} 800:10=x:8 \\ 10x=800\times 8 \\ x=\frac{6400}{10} \\ x=640 \end{gathered}$$

Hence it will covers $640km$ in $8hours$.
