Which car has the greatest efficiency?(1 point)

a 900 kg car that travels 15 km per liter of
fuel
a 1,200 kg car that travels 15 km per liter
of fuel
a 1,200 kg car that travels 20 km per liter
of fuel
a 900 kg car that travels 20 km per liter of
fuel

To determine the car with the greatest efficiency, we need to calculate the fuel consumption per kilometer for each car.

For the first car:
Fuel consumption per kilometer = 1 liter of fuel / 15 km = 0.0667 liters/km

For the second car:
Fuel consumption per kilometer = 1 liter of fuel / 15 km = 0.0833 liters/km

For the third car:
Fuel consumption per kilometer = 1 liter of fuel / 20 km = 0.05 liters/km

For the fourth car:
Fuel consumption per kilometer = 1 liter of fuel / 20 km = 0.0556 liters/km

The car with the greatest efficiency is the third car, a 1,200 kg car that travels 20 km per liter of fuel.
