    Answer: 6:00pm

    Therefore the time on Pete's clock would be

    6:00am + 12 hours

    = 6:00pm

    Step-by-step explanation:

    Given that the clock advances 19 hours in 12 hours.

    Number of days between june 1st and july 1st = 30 days.

    Number of 12 hours between June 1st and July 1st = 30 * 2 = 60

    (there are 24 hours in a day, so there is 2 * 12 hours in a day)

    For the normal clock, in 30 days it would have moved

    60 * 12 hours = 720 hours

    For pete's clock, in 30 days it would have moved

    60 * 19 = 1140 hours

    The amount of extra hours Pete's clock would have moved is

    1140-720 = 420 hours

    Number of Extra 24 hours moved is

    420/24 = 17.5

    So Pete's clock have moved;

    17 (24) + 0.5 (24)

    17 days + 12 hours

    Therefore the time on Pete's clock would be

    6:00am + 12 hours

    = 6:00pm

    (Though in case of an analogue clock 6:00 am and 6:00pm may be seen as the same)

    12 PM

    Step-by-step explanation:

    Given:

    Pete's clock advances by 19 hours for for every 12 hrs.

    As, 1 Day = 24 hrs

    Number of slots of 12 hrs in 1 day = 2

    Number of slots of 12 hours in June month = 2*Number of days in June

    Number of slots of 12 hours in June month = 2*30 = 60

    Hence, from 1st June to 1st July, no of advancing hours given by:

    Total advance hours = 60*19 = 1140

    1140 / 24 = 47.5

    47 gives full days 0.5 gives 6 hours extra.

    So, it will read 6 hours more than actual time.

    Clock reads : 12 pm
