Clock hand degree turns

Answers and reasoning. Review before teaching.

1. 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.
2. Through how many degrees does the hour hand of an analog clock turn in 2 hours?
60°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 2 hours it turns 2 × 30° = 60°.
3. Through how many degrees does the hour hand of an analog clock turn in 3 hours?
90°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 3 hours it turns 3 × 30° = 90°.
4. What is the mirror image time of 3:00 on a 12-hour analog clock?
9:00
Reflecting 3:00 across the vertical 12–6 axis gives 12 − 3 = 9:00.
5. 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°.
6. What is the mirror image time of 10:00 on a 12-hour analog clock?
2:00
Reflecting 10:00 across the vertical 12–6 axis gives 12 − 10 = 2:00.
7. 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°.
8. 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.
9. 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°.
10. 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.
11. 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.
12. Through how many degrees does the hour hand of an analog clock turn in 6 hours?
180°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 6 hours it turns 6 × 30° = 180°.
