Which car has the greatest efficiency? a 900kg car that travels 20K per liter of fuel a 12 00 kg card that travels 20K per liter of fuel. I think it would be the lighter car the 900 kg that can travel 20K per liter of fuel

Answer 1

Yes, you are correct. The car with the greatest efficiency would be the 900kg car that can travel 20 kilometers per liter of fuel. Since it is lighter than the 1200kg car and can travel the same distance on the same amount of fuel, it requires less energy and is therefore more fuel-efficient.
