Clock

 A clock is a circular object with three hands: an hour hand, a minute hand, and a second hand. Horology is the scientific study of clocks.

[A clock's twelve equal divisions]

# The angle formed by any two successive divisions is equal to (360°)/12, or 30°.

[Clock's angle divisions]

A detailed examination of a clock reveals that there are five more divisions in the angular space between any two consecutive divisions. 5 minutes are equal to the space between the two divisions. The angular value of a minute will be obtained by diving the 30° by five.

A minute's angle is equal to (30°)/5=6°.

[Angular minutes values]

The angular values for the first ten minutes are shown in the table below:

Minute(s)	Angular values
1	6°
2	12°
3	18°
4	24°
5	30°
6	36°
7	42°
8	48°
9	54°
10	60°

Problems with clocks are divided into four modules:

• Time Point (or) Time Angle
• Point Time (or) Angle Time
• Reflect Time (or) Mirror Time
• Slow Quick Clocks (or)Slow Fast Clocks
