Question

A car covers a distance of 14.75 km in one litre of petrol. How much distance will it cover in 15.5 litres of petrol?

Answer 1

Distance travelled by the car in 1 litre of petrol = 14.75 km

∴ Distance travelled by the car in 15.5 litres of petrol = $14.75\times 15.5$

= $\frac{1475}{100}\times \frac{155}{10}$
= $\frac{228625}{1000}$
= 228.625 km

Thus, the car travelled 228.625 km in 15.5 litres of petrol.
