Clock hand degree turns

Answers and reasoning. Review before teaching.

1. Through how many degrees does the hour hand of an analog clock turn in 9 hours?
270°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 9 hours it turns 9 × 30° = 270°.
2. What is the mirror image time of 5:00 on a 12-hour analog clock?
7:00
Reflecting 5:00 across the vertical 12–6 axis gives 12 − 5 = 7:00.
3. What is the mirror image time of 9:00 on a 12-hour analog clock?
3:00
Reflecting 9:00 across the vertical 12–6 axis gives 12 − 9 = 3:00.
4. Through how many degrees does the hour hand of an analog clock turn in 10 hours?
300°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 10 hours it turns 10 × 30° = 300°.
5. What is the mirror image time of 7:00 on a 12-hour analog clock?
5:00
Reflecting 7:00 across the vertical 12–6 axis gives 12 − 7 = 5:00.
6. What is the mirror image time of 8:00 on a 12-hour analog clock?
4:00
Reflecting 8:00 across the vertical 12–6 axis gives 12 − 8 = 4:00.
7. What is the mirror image time of 4:00 on a 12-hour analog clock?
8:00
Reflecting 4:00 across the vertical 12–6 axis gives 12 − 4 = 8:00.
8. What is the mirror image time of 2:00 on a 12-hour analog clock?
10:00
Reflecting 2:00 across the vertical 12–6 axis gives 12 − 2 = 10:00.
9. What is the mirror image time of 11:00 on a 12-hour analog clock?
1:00
Reflecting 11:00 across the vertical 12–6 axis gives 12 − 11 = 1:00.
10. Through how many degrees does the hour hand of an analog clock turn in 1 hour?
30°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 1 hour it turns 1 × 30° = 30°.
11. What is the mirror image time of 6:00 on a 12-hour analog clock?
6:00
Reflecting 6:00 across the vertical 12–6 axis gives 12 − 6 = 6:00.
12. Through how many degrees does the hour hand of an analog clock turn in 8 hours?
240°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 8 hours it turns 8 × 30° = 240°.
