Determine 28391
Determine the angle that the large hand makes with the small hand of the clock - the central angle at 12:30. Determine the size of the smaller angle (if possible).
(Help: it's enough if you calculate how big an angle the hands make if they are 1 minute apart. A circle has 360°, and an hour has 60 minutes)
