Funny clock !

P 18  191007

This happens to be a funny clock. The minute-hand moves in the regular, clock-wise direction, but the hour-hand moves in the anti-clock-wise direction. The movements are otherwise normal, i.e. the minute hand takes 60 minutes to cover 360 degrees and the hour hand takes 12 hours.
Find graphically the points of time they will meet in a 12 hour cycle, starting exactly at a time when both have coincided at 12. The timings of coincidence will be read as in any normal clock, set simultaneously at 12.
