A clock shows the time 12:40
The hour hand is 0.8m long and the minute hand is 1.4m long.

All the way around is 60 minutes
The fraction of the way around at
12:40 is +40%2F60+=+2%2F3+
-------------------------
All the way around is also 360 degrees
+%282%2F3%29%2A360+=+240+ degrees is the angle
that the minutes hand has gone around
----------------------------------
The hour hand travels 5 minutes on the clock
when the minute hand travels 60 minutes,
so this fraction, +5%2F60+=+1%2F12+ must be
multiplied by the angle that the minute
hand has traveled.
+%281%2F12%29%2A240+=+20+
----------------------
The minute hand has moved through 20 degrees
from 12:00 to 12:40
