Calculate the rate of fuel consumption.

The rate of fuel consumption is the distance traveled divided by the fuel used.

$$\text{Rate} = \frac{\text{Distance}}{\text{Fuel used}} = \frac{11.45 \text{ km}}{1.12 \text{ litres}}$$ $$\text{Rate} \approx 10.223214 \text{ km/litre}$$

Rounding to 3 significant figures (due to 1.12 litres having 3 s.f.):

$$\text{Rate} \approx 10.2 \text{ km/litre}$$
