Mastering Elapsed Time Concepts

The video tutorial explains the concept of elapsed time, which is the duration between the start and end of an activity. It highlights the importance of understanding elapsed time for effective time management and planning. The tutorial introduces two methods to solve elapsed time problems: using a cut-out clock with movable hands and a T-chart. Through examples, it demonstrates how to calculate elapsed time for various scenarios, including movie start times and bus rides. The video also covers advanced calculations involving larger time units like days and years, emphasizing the versatility of the methods taught.
