720 miles

Step-by-step explanation:

A car uses 8.4 liters of petrol for a 112 mile journey.

In 1 litres = $\dfrac{112}{8.4}\ \text{miles}$ of journey

We need to find far should the car be able to travel on a full tank of petrol i.e. 54 litres of petrol.

$54\ l=\dfrac{112}{8.4}\times 54\\\\=720\ \text{miles}$

So, the car can travel 720 miles when it holds 54 lirres of petrol.
