Define a class, Car, that inherits from Vehicle.
In the Car class, override the drive method so that it decreases the car's fuel by distance * 0.05 and adds distance to mileage
Create an instance of Car, call its drive and refuel methods, and observe the fuel change.

Define a class, Car, that inherits from Vehicle.
In the Car class, override the __str__ method so that it returns a string with car's brand and mileage.
In the Car class, override the refuel method so that it increases the car's fuel by liters * 1.2
Create an instance of Car, call its refuel method, and print the car.
