Directions: Study the information and answer the following question.
There are eight athletes in a sports academy, all connected by their training schedules. Each athlete specializes in a unique sport, and their weekly training hours are different.
Athlete A is the team captain. The training hours of Athlete M (A’s mentor) are the sum of A’s training hours and the training hours of another team member, Athlete E. The training hours of Athlete A are P hours. Athlete A's partner, Athlete B, trains 2 hours less than A. Athlete A also coaches two juniors: Athlete S and Athlete D. The training hours of Athlete S are more than those of Athlete D. The difference in their training hours is the same as the difference in the training hours of A and B.
Another athlete in the team, Athlete C, has training hours Q, which are double the training hours of Athlete S. Athlete E, a veteran member of the team, trains for 22 hours, which is 4 hours less than the combined training hours of Athlete S and Athlete D. The training hours of Athlete B are three times those of Athlete S. Athlete A trains more hours than Athlete B. The head coach, Athlete F, trains for R hours, which is equal to the sum of the training hours of Athlete B and Athlete C.
Quantity I: The average weekly training hours of Athlete M, Athlete S, and Athlete E combined, minus the weekly training hours of Athlete C.
Quantity II: Half the difference between the sum of weekly training hours of Athletes A and F, and the sum of weekly training hours of Athletes D and C.
Quantity III: The square of the difference between the weekly training hours of Athletes F and M, multiplied by the difference of weekly training hours of Athletes S and D.
