How long will 100 yuan of gas last in the United States? The answer varies significantly depending on factors such as fuel efficiency, vehicle type, and current gas prices. Generally, 100 yuan can buy approximately 4 to 5 gallons of gasoline in the U.S., assuming an average price of around $2.50 per gallon. This translates to about 20 to 25 miles per gallon (mpg) for a typical passenger vehicle. Therefore, 100 yuan of gas would typically last between 80 and 125 miles, assuming optimal driving conditions and fuel efficiency.

The duration 100 yuan of gas will last is influenced by several factors:

1. Fuel Efficiency: Vehicles with higher fuel efficiency will travel further on a given amount of fuel. For instance, a car with 30 mpg will travel 150 miles on 5 gallons, whereas a car with 20 mpg will travel only 100 miles on the same amount of fuel.

2. Vehicle Type: Different types of vehicles have varying fuel efficiency. For example, a small, fuel-efficient compact car can achieve up to 40 mpg, while a larger, less fuel-efficient SUV might only get 20 mpg.

3. Current Gas Prices: The price of gasoline fluctuates constantly due to market conditions, geopolitical events, and supply and demand. Higher gas prices mean that 100 yuan will buy less fuel, thus reducing the distance it can cover.

According to the U.S. Energy Information Administration (EIA), the average fuel economy for new vehicles in the U.S. was 25.4 mpg in 2021. This means that a vehicle with an average fuel efficiency would travel approximately 125 miles on 100 yuan of gas, assuming an average gas price of $2.50 per gallon.

It's important to note that these calculations are based on average values and can vary significantly depending on individual circumstances. For a more accurate estimate, one would need to consider the specific fuel efficiency of their vehicle and the current gas prices in their area.
