Clock Rotations and Time Concepts

The video tutorial explains how to determine the time passed between two clock checks. Initially, Risa checks the clock and sees the hour hand at 6 and the minute hand at 0, indicating 6:00. Later, the hour hand is between 6 and 7, and the minute hand has moved halfway, indicating 30 minutes have passed. This is explained as a half-hour. In another instance, the hour hand points at 7, and the minute hand completes a full rotation, indicating 60 minutes or one hour has passed. The tutorial emphasizes understanding half and full rotations of the clock to calculate time intervals.
