Pick a range of times that fits the spread of your movie lengths nicely. Make sure you have at least 5 classes that cover all possible times between your shortest movie and your longest movie. Make sure that all the classes (with the exception of the first and/or last class under extreme circumstances) have the same range.
I don't understand what i'm supposed to be doing. What do I need to do to make these classes?
