PROBLEMS ON CLOCKS SHORTCUT TRICKS HAND WRITTEN NOTE

In this article, we are going to discuss the concept of clocks. Usually, 3 types of questions are asked from this topic. 


Type 1: Finding the time when the angle between the two hands is given.

Type 2: Finding the angle between the 2 hands at a given time.

Type 3: Questions on clocks gaining/losing time.

CLOCKS & TIME SHORTCUT TRICK

Basic Concept of Clocks.

A clock is a complete circle having 360 degrees. It is divided into 12 equal parts i.e. each part is 360/12 = 30°. 
As the minute hand takes a complete round in one hour it covers 360° in 60 min.
In 1 minute it covers 360/60 = 6°/ minute. 
Also, as the hour hand covers just one part out of the given 12 parts in one hour. This implies it covers 30° in 60 min. i.e. ½° per minute. 
This implies that the relative speed of the minute hand is 6 - ½ = 5 ½ degrees. 
We will use the concept of relative speed and relative distance while solving problems on clocks.
