Question
Which car has the highest efficiency? (Assume all cars have the same mass.)(1 point)
Responses

a car that traveled 20 kilometers on 2 liters of gas
a car that traveled 20 kilometers on 2 liters of gas

a car that traveled 25 kilometers on 1 liter of gas
a car that traveled 25 kilometers on 1 liter of gas

a car that traveled 20 kilometers on 1 liter of gas
a car that traveled 20 kilometers on 1 liter of gas

a car that traveled 25 kilometers on 2 liters of gas

Answer 1

To determine which car has the highest efficiency, we can calculate the distance traveled per liter of gas for each option.

1. **Car that traveled 20 kilometers on 2 liters of gas:**
- Efficiency = 20 km / 2 L = 10 km/L

2. **Car that traveled 25 kilometers on 1 liter of gas:**
- Efficiency = 25 km / 1 L = 25 km/L

3. **Car that traveled 20 kilometers on 1 liter of gas:**
- Efficiency = 20 km / 1 L = 20 km/L

4. **Car that traveled 25 kilometers on 2 liters of gas:**
- Efficiency = 25 km / 2 L = 12.5 km/L

Now, comparing the efficiencies:
- Car 1: 10 km/L
- Car 2: 25 km/L
- Car 3: 20 km/L
- Car 4: 12.5 km/L

The car with the highest efficiency is the **car that traveled 25 kilometers on 1 liter of gas** (25 km/L).
