The hour hand of a clock moves 30 degrees in one hour, as it completes a full 360-degree rotation in 12 hours. Some participants initially calculated its movement as 1/60th of a degree per minute, leading to confusion. However, the correct calculation shows that it moves 1/2 degree per minute, totaling 30 degrees in an hour. The discussion also referenced a quiz question that incorrectly stated the hour hand moves only 1 degree in an hour. Overall, the consensus clarifies the hour hand's movement in relation to time and degrees.
