    1:05:5/11 I think.

    During 12 hours, 11 times of overlapping. so each duration of overlapping is 12/11=1 and 1/11 hour. So the first time of overlapping after noon is 13:05:5/11

    At noon, minute and hour hand are at 12 or 0 degrees.

    if we visualize a clock moving, we can see that they cross somewhere between 1pm and 2pm

    at 1pm, the minute hand is at 12 (0 degrees) and the hour hand is at 1 (360/12=30 degrees)

    find the angular velocity of each hand to find each angle in terms of time (minutes)

    minute hand: goes 360 degrees per hour or 360 degrees per 60minites. so the angular velocity is 360/60=6 degrees per minute

    hour hand: goes 360 degrees in 12 hours or 360 degrees per 720 minutes or 1/2 degree per minute

    at 1pm (minute at 0 degrees and hour at 30 degrees)

    angleminute=6t

    angle hour=0.5t+30

    find when equal

    angleminute=angle hour

    6t=0.5t+30

    5.5t=30

    t=5.454 ... = 5 and 45/99 minutes

    that was from 1pm which was 1hr from noon

    so the answer is after 1hr and 5.45 minutes, they will cross again
