The document describes the implementation of a 'Car' class to simulate fuel usage. It requires attributes for fuel efficiency and fuel amount, with methods to drive a distance, get the current fuel level, and add fuel. The constructor initializes the efficiency and sets the gas tank to zero by default.

1. 4. Implement a class, Car, which represents a car and can simulate its fuel usage. The fuel
efficiency should be specified when the object is created. The class should contain the following.
Constructor - init_(self, efficiency) Instance Variables - fuelEfficiency fuel efficiency (measured
in km/ litres); float - fuel amount of gas in tank (litres) with an initial value of zero; float
Methods - drive (distance) -simulates driving the car for certain distance, reducing the fuel level
in the gas tank based on the fuel efficiency - getGaslevel() - returns the current fuel level -
addGas (amount) adds amount to instance variable fuel
