            ●    The minute hand goes from one number to the next in 5 minutes.

            ●    When the minute hand is at 12, it shows the hour of a day.
            ●    When it is at 1, it shows 1 × 5 = 5 minutes past the hour.

            ●    When it is at 3, it shows 3 × 5 = 15 minutes or quarter past the hour.

            ●    When it is at 6, it shows 6 × 5 = 30 minutes or half past the hour.
            ●    When it is at 9, it shows 9 × 5 = 45 minutes past the hour.


            Half Past


            When the minute hand is at 6 and the hour hand is litt le beyond any number, we read
            the time as half past that number. For example, in the following clocks the time is read
            as shown:


                         12                                         12                                   12
                     11     1                                   11     1                             11     1
                   10          2                              10          2                        10          2
                  9             3                            9             3                       9            3

                      7  6  5                                    7  6  5                              7  6   5

              Half Past 2 or 2:30                        Half Past 10 or 10:30                 Half Past 7 or 7:30


            Quarter Past

            When the minute hand is at 3 and the hour hand is litt le beyond any number, we read
            the time as quarter past that number. For example, in the following clocks the time is
            read the given as shown:
   169   170   171   172   173   174   175   176   177   178   179
