H Morton, Lille:
It takes 60 minutes for the hour hand to get from 15 past to 20 past.
So it will take 12 minutes to get from 19 past to 20 past.
So the minute hand is currently pointing at 12 minutes to the hour.

Martin F, Manchester M21:
Each minute interval that the hour hand points to is equivalent to12 minutes, so a 1 minute interval away from the 4th hour for the hour hand is equivalent to a real 12 minutes to the hour for the minute hand.
