To determine which car achieved the greatest efficiency, we need to calculate the fuel efficiency (in kilometers per liter) for each situation.
-
Car 1: 80 kilometers on 5.0 liters
Efficiency = 80 km / 5.0 L = 16 km/L -
Car 2: 80 kilometers on 5.0 liters
Efficiency = 80 km / 5.0 L = 16 km/L -
Car 3: 70 kilometers on 5.0 liters
Efficiency = 70 km / 5.0 L = 14 km/L -
Car 4: 70 kilometers on 5.0 liters
Efficiency = 70 km / 5.0 L = 14 km/L -
Car 5: 50 kilometers on 4.0 liters
Efficiency = 50 km / 4.0 L = 12.5 km/L -
Car 6: 90 kilometers on 6.0 liters
Efficiency = 90 km / 6.0 L = 15 km/L
Now we compare the efficiencies:
- Car 1: 16 km/L
- Car 2: 16 km/L
- Car 3: 14 km/L
- Car 4: 14 km/L
- Car 5: 12.5 km/L
- Car 6: 15 km/L
The greatest efficiency was achieved by Car 1 and Car 2, both with an efficiency of 16 km/L.
