The following table represents the distance travelled by different vehicles using $1 \mathrm{litre}$ of various types of fuel.

Type of vehicle	Ordinary petrol	Premium petrol	Diesel
Car	$13 \mathrm{km}$	$15 \mathrm{km}$	$17 \mathrm{km}$
Bus	$5 \mathrm{km}$	$7 \mathrm{km}$	$6 \mathrm{km}$
$3$ Wheeler	$10 \mathrm{km}$	$12 \mathrm{km}$	$10 \mathrm{km}$

Find the average distance covered by the car in $1 \mathrm{litre}$ of fuel (in $\mathrm{km}$)?
