estimates the distance a car travel at 100 km/h during your reaction time in braking
If the second car has a fuel efficiency that is 45 percent of the first car, we first need to determine the fuel efficiency of the first car, which is 15 km/L. To find the fuel efficiency of the second car, we calculate 45% of 15 km/L: (0.45 \times 15 = 6.75) km/L. Thus, the fuel efficiency of the second car is 6.75 km/L.

You need to know the fuel efficiency of the vehicle when you are driving (driving styles do make a difference).Use the fuel efficiency to calculate the amount of gas you will need and then use the gas price to calculate the cost of fuel.You need to know the fuel efficiency of the vehicle when you are driving (driving styles do make a difference).Use the fuel efficiency to calculate the amount of gas you will need and then use the gas price to calculate the cost of fuel.You need to know the fuel efficiency of the vehicle when you are driving (driving styles do make a difference).Use the fuel efficiency to calculate the amount of gas you will need and then use the gas price to calculate the cost of fuel.You need to know the fuel efficiency of the vehicle when you are driving (driving styles do make a difference).Use the fuel efficiency to calculate the amount of gas you will need and then use the gas price to calculate the cost of fuel.
That depends heavily on the fuel efficiency of the car you are using and the type of driving.If you know how many Miles per Gallon (MPG) your vehicle gets, you can calculate the fuel like this:Miles / MPG = GallonsThat depends heavily on the fuel efficiency of the car you are using and the type of driving.If you know how many Miles per Gallon (MPG) your vehicle gets, you can calculate the fuel like this:Miles / MPG = Gallons
Energy efficiency is typically calculated as the ratio of useful energy output to total energy input. The equation to calculate energy efficiency is: Energy Efficiency = (Useful Energy Output / Total Energy Input) x 100%.
