    Answer:

    42 minutes

    Explanation:

    The total amount of anything expressed in percentage is 100%.

    The reason for this is that per cent means per hundred.

    So, 100% is

    =

    100

    =

    , which is a whole.

    Moving to the question, a total of 25% + 5% = 30% of the time is used up by commercials and credits.

    The time left for the program is 100% – 30% = 70%.

    This is 70% of 60 minutes or
