DIAL
The dial of a clock is a circle whose
circumference is divided into 12 equal parts,
called hour spaces. Each hour space is further
divided into 5 parts, called minute spaces.
This way, the whole circumference is divided
into 12 × 5= 60 minute spaces.

8. COMPETITIVE LENS KAMALINI MAM
For SSC CGL, CPO, MTS, CHSL & OSSC CGL, CHSL
In an hour, the hour-hand moves a distance
of 5 minute spaces whereas the minute-hand
moves a distance of 60 minute spaces. Thus
the minute-hand remains 60- 5 = 55 minute
spaces ahead of the hour-hand.

•We know that the hour hand rotates
0.5° in one minute.
•Also, we know that the minute hand
rotates 6° in one minute.
•Thus, the relative rotation of hour hand
and minute hand is 5.5° per minute.

50. COMPETITIVE LENS KAMALINI MAM

The time taken by the hour hand (smaller hand)
to cover a distance of an hour space is equal to
the time taken by the minute hand (longer hand)
to cover a distance of the whole circumference.
Thus, we may conclude that in 60 minutes, the
minute hand gains 55 minutes on the hour hand.
Also, we may conclude that in 65 (5/11) minutes,
the minute hand gains 60 minutes on the hour
hand.

TYPE-3: FAST AND SLOW
A "fast" clock means it's displaying a time later than the actual time.
Conversely, a "slow" clock is showing a time earlier than the actual time.
These terms refer to the discrepancy between what the clock displays
and the correct time.
Fast Clock:
When a clock is running fast, it gains time. For instance, if a normal clock
would cover 60 minutes, a faster clock might cover more than 60
minutes in that same time.
Slow Clock:
When a clock is running slow, it loses time. If a normal clock would cover
60 minutes, a slower clock might cover less than 60 minutes in that same
time.
