Clock hand degree turns

Answers and reasoning. Review before teaching.

1. 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.
2. Through how many degrees does the hour hand of an analog clock turn in 5 hours?
150°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 5 hours it turns 5 × 30° = 150°.
3. 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°.
4. 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.
5. Through how many degrees does the hour hand of an analog clock turn in 7 hours?
210°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 7 hours it turns 7 × 30° = 210°.
6. 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°.
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. 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°.
9. 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.
10. Through how many degrees does the hour hand of an analog clock turn in 11 hours?
330°
The hour hand turns 360° ÷ 12 = 30° per hour, so in 11 hours it turns 11 × 30° = 330°.
11. 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.
12. 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°.
