# Clock Aptitute Important Formula – Quantitative Aptitude

**Clock Formula :**

**Minute Spaces:**

The face or dial of watch is a circle whose circumference is divided into 60 equal parts, called minute spaces.

**Hour Hand and Minute Hand:**

A clock has two hands, the smaller one is called the hour hand or short hand while the larger one is called minute hand or long hand

- In every hour, both the hands coincide once.

- The hands are in the same straight line when they are coincident or opposite to each other.
- When the two hands are at right angles, they are 15 minute spaces apart.
- When the hands are in opposite directions, they are 30 minute spaces apart.
- Angle traced by hour hand in 12 hrs = 360°
- Angle traced by minute hand in 60 min. = 360°.
- If a watch or a clock indicates 8.15, when the correct time is 8, it is said to be 15 minutes
*too fast*.On the other hand, if it indicates 7.45, when the correct time is 8, it is said to be 15 minutes*too slow*.
