Understanding Time Difference
To find the time difference between 3:45 PM and 6:30 PM, we need to break down the hours and minutes.
Step 1: Identify the Times
- Start Time: 3:45 PM
- End Time: 6:30 PM
Step 2: Break Down the Hours
1. From 3:45 PM to 4:00 PM:
- Remaining minutes: 15 minutes (from 45 to 60)
2. From 4:00 PM to 6:00 PM:
- Total hours: 2 hours
3. From 6:00 PM to 6:30 PM:
- Remaining minutes: 30 minutes
Step 3: Combine the Time
- Total Time = Minutes from 3:45 PM to 4:00 PM (15 minutes) + Hours from 4:00 PM to 6:00 PM (2 hours) + Minutes from 6:00 PM to 6:30 PM (30 minutes)
- Calculate the total:
- 2 hours
- 15 minutes + 30 minutes = 45 minutes
Final Calculation
- Total time difference = 2 hours and 45 minutes.
Therefore, the correct answer is option C: 2 hours 45 minutes.
This method of breaking down the time into manageable parts helps in understanding how to calculate time differences effectively.
