In which situation did the car achieve the greatest efficiency? (Assume the cars all have the same mass.)
a car that traveled 80 kilometers on 5.0 liters of gas
To determine the greatest efficiency, we need to calculate the fuel efficiency of each car. Fuel efficiency is typically measured in kilometers per liter (km/L).
For the given car:
Distance traveled = 80 kilometers
Fuel consumed = 5.0 liters
Fuel efficiency = Distance traveled / Fuel consumed
= 80 km / 5.0 L
= 16 km/L
Therefore, the car that traveled 80 kilometers on 5.0 liters of gas achieved the greatest efficiency with 16 km/L.
To determine which car achieved the greatest efficiency, we need to compare the fuel consumption of different cars. Efficiency is typically measured in terms of fuel consumption per unit of distance.
1. Start by calculating the fuel consumption rate for each car. This is done by dividing the amount of fuel (in liters) by the distance traveled (in kilometers).
- Car A: 5.0 liters / 80 kilometers = 0.0625 liters/kilometer
2. Now, compare the fuel consumption rates of each car. The car with the lowest fuel consumption rate will have achieved the greatest efficiency.
- Car A: 0.0625 liters/kilometer
In this case, the car that achieved the greatest efficiency is Car A, which traveled 80 kilometers on 5.0 liters of gas. The lower the fuel consumption rate, the higher the efficiency.
