    12¼ hours

    Step-by-step explanation:

    The complete work will be 100% so the combination of efforts of Nancy and John would require more hours.

    Given that the duration of 22¾ represent 65% then using the concept of cross multiplication, we first get the total number of hours required for the whole task.

    If 65% represent 22¾ hours then what would 100% represent?

    65%=22¾

    100%=x

    X=100*22¾ / 65=35 hours

    Remaining hours will be 35-22¾ = 12¼ hours

    Therefore, additional 12¼ hours are needed by Nancy and John
