Question

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

Answer 1

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**.
