The hour hand moves 360 degrees in 12 hours (720 minutes). In 1 minute, it moves 360/720 = 0.5 degrees. In 10 minutes, it moves 10 * 0.5 = 5 degrees.
The hour hand completes a full 360 degree circle in 12 hours, which is 720 minutes. Using the formula for the hour hand's speed, we divide 360 by 720 to get a speed of 0.5 degrees per minute. Multiplying this speed by the given 10 minutes yields an angle of 5 degrees.
