You have been named the Good Reader in your town’s reading club. You’re invited to give a 15-minute speech at the annual reception. You want to spend the speech talking about three themes; (1) how you came to love books, (2) the camaraderie you feel in the club, and (3) your long-term goals for encouraging reading in the town. You would like to spend at least 2 minutes talking about each theme. How many ways can you segment your time so that you talk enough about each theme? Note that you should assume the number of minutes you spend talking about each theme is a natural number. One example of a valid breakdown is 3 minutes on theme 1, 5 minutes on them 2, and 7 minutes on theme 3. Describe how you arrived at your solution.
