The angle between the minute hand and the hour hand at 12:20 is 120 degrees.

At 12:20 the minute hand has moved 120° if we consider 12:00 as 0°

Each hour the hour hand moves 30°

At that time of 12:20 the hour hand has moved 20/60 or 1/3 of its 30° movement, so the hour hand has moved 10°

making the angle between the 20 at 12:20 equal to 110°

My last sentence makes no sense, it should say

making the angle between the hands at 12:20 equal to 110°
