Question

A vehicle covers a distance of $43.2km$ in $2.4litres$of petrol. How much distance will it cover in one litre of petrol?

Answer 1

From the given details we get to know that

Total distance covered by the vehicle in $2.4litres$ of petrol $=43.2km$

Distance covered in one liter of petrol $=43.2÷2.4$

First, let us convert the decimals into fraction

$43.2=\frac{432}{10}$$;2.4=\frac{24}{10}$

So,$43.2÷2.4$ $=\left(\frac{432}{10}\right)÷\left(\frac{24}{10}\right)$

Taking reciprocal of $\frac{24}{10}$ and multiplying we get,

$$\begin{gathered} =\left(\frac{432}{\cancel{10}}\right)\times \left(\frac{\cancel{10}}{24}\right) \\ =\frac{432}{24} \\ =\frac{18}{1} \\ =18km \end{gathered}$$

Hence, the total distance covered by one litre of petrol is $18km.$
