Question

A car travels 432 km on 48 litres of petrol. How far would it travel in 20 litres of petrol?

Answer 1

Let the distance covered by the car be $xkm$.

$\Rightarrow \frac{48}{20}=\frac{432}{x}$ (1 mark)

$\Rightarrow x=\frac{20\times 432}{48}$

$\Rightarrow x=180km$ (1 mark)

Hence, the car can cover 180 km in 20 litres of petrol.
