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