In which situation did the car achieve the greatest efficiency? (Assume the cars all have the same mass.)(1 point) Responses a car that traveled 80 kilometers on 5.0 liters of gas a car that traveled 80 kilometers on 5.0 liters of gas a car that traveled 70 kilometers on 5.0 liters of gas a car that traveled 70 kilometers on 5.0 liters of gas a car that traveled 50 kilometers on 4.0 liters of gas a car that traveled 50 kilometers on 4.0 liters of gas a car that traveled 90 kilometers on 6.0 liters of gas

To determine which car achieved the greatest efficiency, we need to calculate the fuel efficiency (in kilometers per liter) for each situation.

  1. Car 1: 80 kilometers on 5.0 liters
    Efficiency = 80 km / 5.0 L = 16 km/L

  2. Car 2: 80 kilometers on 5.0 liters
    Efficiency = 80 km / 5.0 L = 16 km/L

  3. Car 3: 70 kilometers on 5.0 liters
    Efficiency = 70 km / 5.0 L = 14 km/L

  4. Car 4: 70 kilometers on 5.0 liters
    Efficiency = 70 km / 5.0 L = 14 km/L

  5. Car 5: 50 kilometers on 4.0 liters
    Efficiency = 50 km / 4.0 L = 12.5 km/L

  6. 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.
