Question 2
A clock is 9 minutes fast. If the correct time is 8:31, what time does the clock show?
If the clock is 9 minutes fast, it shows 8:40 when the correct time is 8:31.
Question 3
A clock gains 2 minutes every hour. If it shows the correct time at 6:00, how many minutes will it be gaining after 12 hours?
The clock gains 2 minutes per hour. After 12 hours: 2 × 12 = 24 minutes.
Question 4
At approximately what time between 8:00 and 9:00 do the clock hands form a right angle (90°)?
The hands form a 90° angle at approximately 9:00.
Question 5
What is the angle between the hour and minute hands of a clock at 6:03?
Hour hand at 181.5°, minute hand at 18°. Difference = 163.5°
Question 6
At approximately what time between 12:00 and 1:00 do the clock hands point in exactly opposite directions (180° apart)?
The hands point in opposite directions (180° apart) at approximately 1:38.
Question 7
What is the water image (vertical mirror reflection) of the clock showing 7:00?
In water reflection, the time appears as 5:00 (calculated as 11:60 - 7:00).
Question 8
At approximately what time between 3:00 and 4:00 do the clock hands point in exactly opposite directions (180° apart)?
The hands point in opposite directions (180° apart) at approximately 4:55.
Question 9
What is the mirror image of 4:40 on a clock?
In a mirror, 4:40 appears as 7:20.
Question 10
At what time between 12:00 and 1:00 do the hour and minute hands exactly overlap?
The hands overlap at 12:33 when both hands are at 196° from 12 o'clock.
Question 11
At approximately what time between 7:00 and 8:00 do the clock hands form a right angle (90°)?
The hands form a 90° angle at approximately 8:27.
Question 12
What is the mirror image of 7:47 on a clock?
In a mirror, 7:47 appears as 4:13.
Question 13
A clock gains 5 minutes every hour. If it shows the correct time at 4:00, how many minutes will it be gaining after 8 hours?
The clock gains 5 minutes per hour. After 8 hours: 5 × 8 = 40 minutes.
Question 14
What is the water image (vertical mirror reflection) of the clock showing 3:00?
In water reflection, the time appears as 9:00 (calculated as 11:60 - 3:00).
Question 15
A clock is 5 minutes slow. If the correct time is 7:05, what time does the clock show?
If the clock is 5 minutes slow, it shows 7:00 when the correct time is 7:05.
Question 16
What time will it be 75 minutes after 8:02?
Starting from 8:02, 75 minutes after gives 9:17.
Question 17
What is the angle between the hour and minute hands of a clock at 1:55?
Hour hand at 57.5°, minute hand at 330°. Difference = 87.5°
Question 18
What is the angle between the hour and minute hands of a clock at 5:04?
Hour hand at 152.0°, minute hand at 24°. Difference = 128°
Question 19
What time will it be 158 minutes before 4:56?
Starting from 4:56, 158 minutes before gives 2:18.
Question 20
What is the water image (vertical mirror reflection) of the clock showing 3:45?
