    Borrow a minute to make 60 more seconds

    17:94
    - 6:58
    ______
    11:36

    The sums of the minutes and seconds separately are

    208:66

    66 seconds becomes 1:06 and added to the minutes we get

    209:06

    209 divided by 60 gives us 3 hours and 29 minutes so the final answer is 3:29:06.
