Question

A car covers a distance of 22.8 km in 2.4 litres of petrol. How much distance will it cover in 1 litre of petrol?

Answer 1

Distance covered by the car with 2.4 litres of petrol = 22.8 km
∴ Distance covered with 1 litre of petrol = $\left(\frac{22.8}{2.4}\right)$ km
= $\left(\frac{228}{24}\right)$ km = $\left(\frac{228÷12}{24÷12}\right)$ km = $\left(\frac{19}{2}\right)$ km = $9\frac{1}{2}$ km

Hence, the distance covered by the car with 1 litre of petrol is $9\frac{1}{2}$ km.
