The best fuel efficiency speed typically falls between 50 to 80 km/h (31 to 50 mph) for most vehicles. Driving within this range allows engines to operate at optimal performance, reducing fuel consumption. Speeds above or below this range often lead to increased drag or inefficient engine operation, resulting in lower fuel efficiency. However, the exact speed can vary depending on the vehicle type and design.

What is the fuel efficiency of a car if it gets 45 percent of the fuel efficiency of another car that travel 15 km on 1 L of gasoline?

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.


how many ltrs at a speed of 10km/hr?

To drive 400 km, you would need to use 40 litres of petrol. This is calculated by dividing the total distance (400 km) by the fuel efficiency of your car (10 km/litre).


How many kilometers can you travel on 50 liter of fuel?

The number of kilometers you can travel on 50 liters of fuel depends on the fuel efficiency of your vehicle, measured in kilometers per liter (km/l). For example, if your vehicle has a fuel efficiency of 10 km/l, you would be able to travel 500 kilometers (50 liters x 10 km/l). However, if your vehicle has a fuel efficiency of 15 km/l, you would be able to travel 750 kilometers (50 liters x 15 km/l). Therefore, the distance you can travel on 50 liters of fuel varies depending on your vehicle's fuel efficiency.


How many liters is needed to drive 4.4km?

The amount of liters needed to drive 4.4 km depends on the vehicle's fuel efficiency, which is usually measured in liters per 100 km. If you know the fuel efficiency of your vehicle, you can calculate the liters needed by dividing the distance by 100 and then multiplying by the fuel efficiency.


What is the most economic speed for a hyundia santa fe?

The most economical speed for a Hyundai Santa Fe typically falls within the range of 50 to 65 miles per hour (80 to 104 km/h). At this speed, the vehicle can achieve optimal fuel efficiency, minimizing air resistance and engine strain. However, fuel economy can also be influenced by factors such as driving conditions and maintenance. For the best results, refer to the owner's manual or fuel economy ratings specific to your model year.

How many stop need a car within 600 km?

The number of stops a car needs within a 600 km journey depends on several factors, including the car's fuel efficiency, the size of its fuel tank, and driving speed. On average, a vehicle may need to stop for fuel every 400-600 km, depending on these variables. Additionally, if the trip requires breaks for rest or meals, more stops may be necessary. Therefore, one to three stops could be typical for such a distance.
