Question
**Transcription:** "Build a formula to subtract the start time from the end time and multiply those results by 24. The result is shown in hours." --- **Explanation for Educational Use:** This instruction is for calculating the difference between two times, generally done to find the duration of an event or activity. To achieve this: 1. **Subtract the Start Time from the End Time:** Determine the time interval by subtracting the start time from the end time. This step gives you the duration as a fraction of a day since times are often stored as fractions (e.g., 0.5 for noon if a day starts at midnight). 2. **Multiply the Result by 24:** Since a full day represents 24 hours, multiplying the fractional day result by 24 converts this to an hour-based format, making it easier to understand and compare durations in an hourly context. This method is useful for calculating time durations in various applications, such as work logs, event planning, or computer time functions.
