To practice working with classes and operators

Create a class called Distance whose objects can store a distance measured in either miles or kilometers. Set up your Distance class so its objects can be added, subtracted, multiplied, or divided by other distance objects.

When the two distance objects that are being worked with are not in the same units a conversion will have to take place. To convert miles to kilometers multiple the value by 1.60934 and to convert kilometers to miles multiple the value by 0.621371

Your distance class is correct when it can run the attached code and produce the following output:
