# How to Define Elapsed Time

Elapsed time is the amount of time that passes from the start of an event to the end of that event. It's simply the difference between the starting time and the ending time.

## A Step-by-step Guide to Defining Elapsed Time

Here’s a step-by-step guide to defining elapsed time:

### Step 1: Understand the Concept of Elapsed Time

Elapsed time is the total time that has passed between a starting point and an ending point. It measures the duration or length of time that has gone by.

### Step 2: Identify the Start Time

Determine the specific time or event when something begins. This could be when you start an activity when a movie begins, or when you leave for school.

### Step 3: Identify the End Time

Determine the specific time or event when something ends. This could be when you finish an activity when a movie ends, or when you arrive at school.

### Step 4: Determine the Time Difference

To find the elapsed time, subtract the start time from the end time. Consider the hours, minutes, and possibly seconds when calculating the time difference.

### Step 5: Write the Elapsed Time

Write the elapsed time in a format that matches the given time units. For example, if the start time is 9:00 AM and the end time is 11:30 AM, the elapsed time would be written as 2 hours and 30 minutes.

By following these steps, you can define and calculate elapsed time for various scenarios. Keep practicing with different start and end times to enhance your understanding of elapsed time.
