Calculation of the Change in Maximum Driving Range

To calculate the change in maximum driving range, we need to consider the difference in fuel efficiency between gasoline with an octane rating of 95 (AI-95) and gasoline with an octane rating of 98 (AI-98). The fuel efficiency is determined by the specific energy content of the fuel, which is measured in megajoules per kilogram (MJ/kg).

Given that the specific energy content of AI-92 gasoline is 42 MJ/kg, we can assume that the specific energy content of AI-95 and AI-98 gasoline is similar. Therefore, we can use the specific energy content of AI-92 gasoline for our calculation.

To calculate the change in maximum driving range, we need to determine the amount of fuel consumed per kilometer for both AI-95 and AI-98 gasoline. We can then compare these values to find the difference.

Let's assume that the vehicle's fuel consumption is constant and does not change with the type of gasoline used. In this case, the fuel consumption per kilometer can be calculated as follows:

Fuel consumption per kilometer = Fuel consumption per liter / Maximum driving range

To find the fuel consumption per liter, we can use the following formula:

Fuel consumption per liter = Fuel consumption per kilometer * Maximum driving range

Let's denote the maximum driving range with AI-95 gasoline as R95 and the maximum driving range with AI-98 gasoline as R98.

Using the given information that the driver bought 20 liters of AI-95 gasoline, we can calculate the maximum driving range with AI-95 gasoline as follows:

R95 = Fuel consumption per liter * 20 liters

Similarly, if the driver had bought 20 liters of AI-98 gasoline instead, the maximum driving range with AI-98 gasoline would be:

R98 = Fuel consumption per liter * 20 liters

To find the change in maximum driving range, we can subtract the maximum driving range with AI-95 gasoline from the maximum driving range with AI-98 gasoline:

Change in maximum driving range = R98 - R95

Now let's calculate the change in maximum driving range using the given information.

Calculation:

Given: - The driver bought 20 liters of AI-95 gasoline.

To calculate the change in maximum driving range, we need to determine the fuel consumption per kilometer. Since we don't have the specific fuel consumption rate, we cannot provide an exact answer. However, we can provide a general approach to calculating the change.

Assuming the fuel consumption rate is constant, we can calculate the fuel consumption per kilometer using the formula mentioned earlier:

Fuel consumption per kilometer = Fuel consumption per liter / Maximum driving range

Let's assume the maximum driving range with AI-95 gasoline is 10 kilometers per liter. Using this assumption, we can calculate the fuel consumption per kilometer:

Fuel consumption per kilometer = 1 liter / 10 kilometers = 0.1 liters/kilometer

Now, we can calculate the maximum driving range with AI-95 gasoline:

R95 = Fuel consumption per liter * 20 liters = 0.1 liters/kilometer * 20 liters = 2 kilometers

Assuming the maximum driving range with AI-98 gasoline is also 10 kilometers per liter, we can calculate the fuel consumption per kilometer:

Fuel consumption per kilometer = 1 liter / 10 kilometers = 0.1 liters/kilometer

Now, we can calculate the maximum driving range with AI-98 gasoline:

R98 = Fuel consumption per liter * 20 liters = 0.1 liters/kilometer * 20 liters = 2 kilometers

Finally, we can calculate the change in maximum driving range:

Change in maximum driving range = R98 - R95 = 2 kilometers - 2 kilometers = 0 kilometers

Therefore, if the driver had bought 20 liters of AI-98 gasoline instead of AI-95 gasoline, the maximum driving range would not have changed.

Please note that the above calculation assumes a constant fuel consumption rate and a specific fuel consumption rate of 10 kilometers per liter for both AI-95 and AI-98 gasoline. The actual fuel consumption rate may vary depending on various factors such as driving conditions, vehicle efficiency, and engine specifications.
