To determine which car has the greatest efficiency, we can analyze the fuel efficiency of each vehicle by looking at how many kilometers they can travel per liter of fuel, regardless of their weight.
- 1,200 kg car: 20 km/l
- 900 kg car: 20 km/l
- 900 kg car: 15 km/l
- 1,200 kg car: 15 km/l
From this information, we can see that the two cars with the highest fuel efficiency are:
- The 1,200 kg car that travels 20 km/l
- The 900 kg car that travels 20 km/l
Both cars have the same fuel efficiency of 20 km/l. The weight of the cars does not affect the fuel consumption in terms of efficiency (km/l), but in general, lighter vehicles may consume less fuel for similar distances.
Since both the 1,200 kg car and the 900 kg car with 20 km/l have the highest efficiency, you could technically consider either to have the greatest efficiency based on kilometers traveled per liter of fuel.
Final answer: Both the 1,200 kg car that travels 20 km/l and the 900 kg car that travels 20 km/l have the greatest efficiency (20 km per liter).
