Clocks

When You are asked to find the time taken by the hands of a clock within an hour you can use this method. For Example Lets Take a Question.

Question:
              At what time will the hands of a clock meet each other between 5 o clock to 6 o clock.


Solution:

              The Question is to find a time between 5 & 6.

So, the hours in the time is definitely 5. We just need to find the minutes alone.

To find the minutes just multiply the Hours with the constant 60/11


                  = 5 * 60 / 11
                                                = 300 / 11
                                                = 27 3/11



We found that the minutes taken is
                                            = 27 3/11

So, that the time during the meeting of the hands is

                                                   = 5: 27 3 / 11


Note: You cannot use this When You are Asked to find the time when a particular angle is formed between hands. you can use it only when the hands meet each other
