📚 Understanding Elapsed Time and Finding End Time
In math, especially when dealing with time, it's important to understand the difference between 'elapsed time' and 'finding the end time.' Let's explore each of these concepts:

⏱️ Definition of Elapsed Time
Elapsed time refers to the amount of time that passes from a starting point to an ending point. It's the duration of an event or activity.

📅 Definition of Finding End Time
Finding the end time means determining what the time will be after a certain amount of time has passed from a known starting time. It involves adding a duration to a specific start time.

Feature
      Elapsed Time
      Finding End Time

Definition
      The amount of time that passes.
      Determining the final time after a duration.

What you're solving for
      How long something took.
      What time something will end.

Operation
      Often involves subtraction (End Time - Start Time).
      Involves addition (Start Time + Elapsed Time).

Example Question
      "How long was the movie?"
      "What time will the movie end?"

Key Takeaways

⏱️ Elapsed Time: Measures the duration of an event. For example, if a game started at 2:00 PM and ended at 3:00 PM, the elapsed time is 1 hour.
     📅 Finding End Time: Determines the future time after a certain duration. For example, if you start reading at 7:00 PM and read for 30 minutes, the end time is 7:30 PM.
     ➕ Operation for End Time: To find the end time, add the elapsed time to the start time.
     ➖ Operation for Elapsed Time: To find the elapsed time, subtract the start time from the end time.
