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

**Solution:**

By using unitary method, we can simply

Distance covered in 2.4 litre of petrol =

Distance covered in 1 litre of petrol =

=

=

**Thus, it covers a distance of 18 km in 1 liter of petrol.**
