Which car has the greatest efficiency?
1) a 900 kg car that travels 20 km per liter of fuel
2) a 900 kg car that travels 15 km per liter of fuel
3) a 1,200 kg car that travels 15 km per liter of fuel
4) a 1,200 kg car that travels 20 km per liter of fuel
it’s the last one
4) The greatest efficiency car is the one that doesn't break down or need any repairs. Just kidding! In all seriousness, the car with the greatest efficiency is the one that travels the longest distance per liter of fuel. So in this case, it's option 4) a 1,200 kg car that travels 20 km per liter of fuel. It's like having a car with legs!
To determine which car has the greatest efficiency, we need to calculate the fuel consumption per kilometer for each car. The lower the fuel consumption per kilometer, the greater the efficiency.
1) The first car weighs 900 kg and travels 20 km per liter of fuel. To calculate the fuel consumption per kilometer, we divide the distance traveled by the amount of fuel consumed. So, the fuel consumption per kilometer for this car is: 1 liter / 20 km = 0.05 liters/km.
2) The second car also weighs 900 kg but travels 15 km per liter of fuel. The fuel consumption per kilometer for this car is: 1 liter / 15 km = 0.067 liters/km.
3) The third car weighs 1,200 kg and travels 15 km per liter of fuel. The fuel consumption per kilometer for this car is: 1 liter / 15 km = 0.067 liters/km.
4) The fourth car weighs 1,200 kg and travels 20 km per liter of fuel. The fuel consumption per kilometer for this car is: 1 liter / 20 km = 0.05 liters/km.
Comparing the values, we see that both the first and fourth cars have the same fuel consumption per kilometer of 0.05 liters/km. Therefore, cars 1 and 4 have the greatest efficiency in terms of fuel consumption.
To determine the car with the greatest efficiency, we need to compare the distance traveled per liter of fuel for each car.
Let's calculate the efficiency for each option:
1) Car 1: 900 kg car that travels 20 km per liter of fuel
2) Car 2: 900 kg car that travels 15 km per liter of fuel
3) Car 3: 1,200 kg car that travels 15 km per liter of fuel
4) Car 4: 1,200 kg car that travels 20 km per liter of fuel
To find the efficiency, we divide the distance traveled by the amount of fuel used:
1) Car 1: 20 km/L
2) Car 2: 15 km/L
3) Car 3: 15 km/L
4) Car 4: 20 km/L
Comparing these options, we can see that both Car 1 and Car 4 have the same efficiency of 20 km per liter of fuel. Therefore, they have the greatest efficiency among the given options.
