            Kelly went to a fun fair with her elder brother. Kelly wanted to ride an elephant.

            But its back was full of children. The man at the ticket window said, It will

            come in just 10 minutes. Please wait in the shadow.

            Kelly asked her brother how much 10 minutes are. Her brother told that it
            would be ten minutes while they sip coconut water.


            As they finished their coconut water, they saw the elephant coming back.

            They happily enjoyed the ride.


            TIME SHOWN BY MINUTE HAND


            When the minute hand moves from 12 to 1, it covers 5 small division. Similarly
            upon reaching 2, it has covered 10 small division; upon reaching 3, it has

            covered 15 small division and so on.


                                                      MINUTE HAND



              at 1 shows        0 1 × 5  = 5 minutes              at 9 shows        0 9 × 5  = 45 minutes
                                              0
              at 2 shows        0 2 × 5  = 10 minutes             at 10 shows  10 × 5 = 50 minutes


              at 3 shows        0 3 × 5 = 15 minutes              at 11 shows 11 × 5  = 55 minutes

              at 6 shows        0 6 × 5  =  30 minutes            at 12 shows 12 × 5  =  60 minutes


              60 minutes indicate the next hour.



            We say these minutes as 5 minutes past the hour, 10 minutes past the hour, 15
            minutes past the hour and so on:

            (i)    When the minute hand moves one-fourth (quarter) of the dial (3 digits =

                   15 minutes, we say the time in quarter past the hour).
