Pseudocode:

read Capacity, MilesPerGallon
MaximumRange:=Capacity*MilesPerGallon
print "Maximum Range = ", MaximumRange

Pseudocode is a way of writing out the logic of a program using human-readable language without focusing on the specific syntax of a programming language. In this case, the pseudocode is written to calculate the maximum range of a vehicle based on its capacity (fuel tank size) and miles per gallon fuel efficiency.

To get the maximum range, you need two input values - Capacity and MilesPerGallon. These values can be entered by the user or provided in some other way as per the specific implementation.

Here's the step-by-step explanation of the pseudocode:

1. Read the input values for Capacity and MilesPerGallon. This can be done by using an input function or by initializing the variables with predefined values.
Example: Capacity = 15, MilesPerGallon = 20

2. Calculate the MaximumRange by multiplying the Capacity and MilesPerGallon.
Example: MaximumRange = 15 * 20 = 300

3. Print the MaximumRange value to display the result.
Example: "Maximum Range = 300"

By following these steps, you can use the pseudocode to calculate and print the maximum range of the vehicle based on the provided values of Capacity and MilesPerGallon.
