To calculate how long Paul was away from home:
- Determine the time he left: 7:25 AM.
- Determine the time he returned: 3:15 PM.
- Calculate the time difference:
- From 7:25 AM to 12:00 PM is 4 hours and 35 minutes.
- From 12:00 PM to 3:15 PM is 3 hours and 15 minutes.
- Add the two time spans:
- 4 hours 35 minutes + 3 hours 15 minutes = 7 hours 50 minutes.
Therefore, Paul was away from home for 7 hours and 50 minutes.
