Taxi Fare

# Program that calculates taxi fares using a function

# Defines the function fare_calculator to calculate the total cost

        The necessary steps for calculation are:
        1. Base fare of $4.00.
        2. Conversion from kilometers to meters.
        3. Divide the meters traveled by 140 meters.
        4. Take the result from Step 3 and multiply it by 0.25.
        5. Take the result from Step 4 and add the base fare.
