Elapsed Time Concepts and Calculations

This video tutorial explains the concept of elapsed time, which is the difference between a starting and ending time. It covers how to read clock hands to determine elapsed time, perform calculations, and solve real-world problems. The tutorial also provides tips for handling more complex time calculations and drawing clock hands for different times.
