From 12pm to 2:30pm, the hour hand goes 75 degrees. It is the minute hand that goes through 795 degrees.
(30 + 4320*k) degrees where k is an integer.
Between 4 o'clock and 6 o'clock the hour hand moves through 60 degrees.
180 degrees.
Every minute is six degrees. At 7:30, the hour hand has moved halfway between the 7 and 8. Call it 15 degrees.

6 degrees. There are 360 degrees in a full circle, and therefore for every second the hand moves through one sixtieth of a circle.
20 degrees
Each hour, it rotates through 30 degrees, every twelve hours, it rotates 360 degrees.
If we simply imagine the minute hand is on the 6, and the hour hand is on the two, there will be a total of 120 degrees between the minute and the hour hand, 1/3 of the clock is covered between the two hands. However, it is not that simple. Because 30 minutes has travelled, the hour hand will be half way between the 2 and the 3. We know that every hour, the hour hand moves 30 degrees (360 / 12 hours = 30). Therefore, in 30 minutes, it will have travelled 15 degrees. Which means the hour hand is 15 degrees closer to the minute hand. Therefore, the actual angle between the minute and hour hand is actually 105 degrees.
6 degrees.
