A clock’s dial is like a broad ring, divided into 12 identical portions, where every single part demonstrates different hours. Every hour space is further segmented in 5 sections – each having a 1 minute time duration. Usually there are two needles that revolve in a clock.
The hour needle shields 1/12 Th boundary of the circle in 1 hour. Alternatively, the minute needle covers just one circumference of the clock per hour.

Formula or Rule for solving CLOCKS questions

Since the minute needle moves at a speed of 55 minutes per hour, therefore in 1 minute, the minute point covers a distance of (55/60) or (11/12) minutes. Therefore the Clock Formula: 11/12 which is essential in finding out the angle between two needles of a clock.

As minute needle covers 360 degrees per hour, covering one full circle. Hence is travels 360/60= 6 degrees/min.
