The hour hand of a clock moves -30 degrees each other. An average college football game takes 3 1/2 hours. Which model demonstrates the number of degrees the hour hand of the clock moves for the average football game?

To solve this problem, we need to determine how many degrees the hour hand of the clock moves during the average duration of a college football game, which is 3 1/2 hours.

### Step 1: Understand the movement of the hour hand
The hour hand of a clock completes a full circle of 360 degrees in 12 hours.

### Step 2: Calculate the degrees moved per hour
To find out how many degrees the hour hand moves per hour, divide the total degrees in a full circle by the total hours:

\[
\text{Degrees per hour} = \frac{360 \text{ degrees}}{12 \text{ hours}} = 30 \text{ degrees per hour}
\]

### Step 3: Convert 3 1/2 hours to a fraction
3 1/2 hours is equivalent to 3.5 hours.

### Step 4: Calculate the total degrees the hour hand moves in 3.5 hours
Multiply the degrees per hour by the duration of the football game:

\[
\text{Total degrees} = 30 \text{ degrees per hour} \times 3.5 \text{ hours} = 105 \text{ degrees}
\]

### Conclusion
The hour hand of the clock moves **105 degrees** during an average college football game.

### Relative Questions
1. How many degrees does the hour hand move in 2 hours?
2. What is the degree movement of the hour hand in 1/4 hour?
3. How many degrees does the hour hand move in 6 hours?
4. How many degrees does the hour hand move in a full 24-hour day?
5. What is the degree movement of the minute hand in one hour?

### Tip
Remember that the hour hand moves 30 degrees per hour, and you can easily calculate its movement over any given time by multiplying this rate by the number of hours.

Find out how many degrees the hour hand of a clock moves during an average college football game, which lasts 3 1/2 hours. This problem involves clock angles and basic time calculations, perfect for students in Grades 6-8.
