SUMMARY
At 10:00, the hour hand of an analog clock is positioned 300 degrees ahead of the minute hand. To determine when the minute hand next aligns with the hour hand, one must apply rotational kinematics principles. The speeds of the hour and minute hands are critical: the hour hand moves at 0.5 degrees per minute, while the minute hand moves at 6 degrees per minute. The next alignment occurs when the minute hand catches up to the hour hand, which can be calculated by setting up an equation based on their relative speeds.
