The Car class has the following private data fields: year built model, make, speed, traveling time, and total kilometers covered Create a constructor with a year, a model and a make. Create all the necessary accessors and mutators for the data fields. Add a method for calculating the total kilometers covered.

In the main method, create a car, start it, and move it for 30 minutes. Next, change the speed to 60km/hour and move it for 60 minute. Then, change the speed to 30km/hour and move it for 20 minutes. At the end, stop the car, and display the car's year built, model, make, and the total kilometers covered. For the sample values given above, the total kilometers covered should be 90
