   While striking 6 the clock strikes its first gong at 6 O’ clock and it strikes 5 more regular intervals. these 5 intervals take 6 seconds so that the intervals between gongs is 6/5 seconds. so strike 12 O’ clock there will be 11 intervals each takes 6/5 seconds .
   so, it takes 11*6/5=13.2 seconds .
