Clock hand degree turns

Answers and reasoning. Review before teaching.

1. 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.
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 7:00 on a 12-hour analog clock?
5:00
Reflecting 7:00 across the vertical 12–6 axis gives 12 − 7 = 5:00.
4. 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°.
5. 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.
6. What is the mirror image time of 1:00 on a 12-hour analog clock?
11:00
Reflecting 1:00 across the vertical 12–6 axis gives 12 − 1 = 11:00.
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. Through how many degrees does the hour hand of an analog clock turn in 12 hours?
360°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 12 hours it turns 12 × 30° = 360°.
9. 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.
10. 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.
11. 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°.
12. Through how many degrees does the hour hand of an analog clock turn in 4 hours?
120°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 4 hours it turns 4 × 30° = 120°.
