Hi! MathLearner. Hope ur having a great time.
ur question can easily be solved by using a small matrix
00:06 11:58 after 36 hrs
one clock is goin forward and other backward even if there min hand come on same position,there hr hand won't. So using matrix for hrs we get
if over all time elapsed is calculated it will be a multiple of 24. Therefore if they were initially set at 12 noon they will again show same time at 12 noon after 180 days
