A car uses 12.8 liters of petrol to travel 100km find the number of kilometers the car travel on 1 litre

To find the number of kilometers the car travels on 1 liter of petrol, we can divide the distance traveled (100km) by the amount of petrol used (12.8 liters).

Therefore, the car travels 100km / 12.8 liters = 7.81 kilometers on 1 liter of petrol.
