_____________________

Answer with explanation:-

In 1 litres of car covers=20 km

In 3$\dfrac{3}{5}$ it will cover=?

3$\dfrac{3}{5}$ can be represented as $\dfrac{18}{5}$ litres

So,

$\dfrac{18}{5}$ litres it will cover=$\dfrac{20}{1}$×$\dfrac{18}{5}$

Therefore by cutting we get is,

$\dfrac{4}{1}$×$\dfrac{18}{1}$

Therefore $\dfrac{4×18}{1}$=72km

Hence, car covers 72km in $\dfrac{18}{5}$litres..
