Real life problems...

Today, when I was sitting and studying on my own, I realized something: I can now start solving real life problems with my engineering knowledge. By real life problems I mean problems that don't include presumtions that air resistance is zero and include a triple integral in the answer. Problems that give understandeable solutions, that's what I mean. And it is quite fun as well:

Mr. Miller is in charge of establishing the weekly timetable for two classes of the last year in a college. The two classes have the same teachers, except for mathematics and sport. In the college all lessons have a duration of two hours. Furthermore, all students of the same class attend exactly the same courses. From Monday to Friday, the slots for courses are the following: 8:00–10:00, 10:15–12:15, 14:00–16:00, and 16:15–18:15. The following table lists the number of two-hour lessons that every teacher has to teach the students of the two classes per week.

The sport lessons have to take place on Thursday afternoon from 14:00 to 16:00. Furthermore, the first time slot on Monday morning is reserved for supervised homework. Mr Effofecks is absent every Monday morning because he teaches some courses at another college. Mrs Insulin does not work on Wednesday. And finally, to prevent students from getting bored, every class may only have one two-hour lesson per subject on a single day. Write a mathematical program that allows Mr Miller to determine the weekly timetable for the two classes.

It is a good thing classes at the Belgrano University have ended because then I have time to finally learn stuff!
