GCSE Maths Practice: compound-measures

Question 1 of 10

This question calculates the fuel efficiency of a car. Fuel efficiency measures how many kilometres a car travels per litre of petrol.

›

\( \begin{array}{l} \text{A car travels 396 km on 36 litres of petrol.} \\ \text{Find its fuel efficiency in km/litre.} \end{array} \)

Choose one option:

\( \text{11 km/litre} \) \( \text{10.5 km/litre} \) \( \text{10 km/litre} \) \( \text{11.5 km/litre} \)

Always convert distance and fuel to the same units. Check your division.

Fuel efficiency is a type of compound measure. Divide distance by fuel to find km per litre.
