Answer:

8km /hr

1/ 8 of a litre.

Explanation:

We are told that Amelia drives 48 kilometres in 6 hours, this means the number of kilometres she drives per litre is

$48\operatorname{km}/6\text{litres}$
$\frac{8\operatorname{km}}{\text{litre}}$

Hence, Amelia drives 8 kilometres per litre.

The next question can be rephrased as, given that Amelia drives 8 km per litre, how many litres will it take to drive one kilometre?

To answer this question, we make use of the equation

$\operatorname{km}\text{ travelled = 8km/litre }\cdot\text{ litres}$

Now, we want

km travelled = 1 km

and the above equation gives

$\begin{gathered} 1=\frac{8\operatorname{km}}{\text{litre}}\cdot\text{litres} \\ 1=8\cdot\text{litres} \end{gathered}$

Dividing both sides by 8 gives

$\text{litres}=(1)/(8)$

Hence, it takes 1/8 of a litre to drive 1 kilometre.
