I'll solve each time conversion problem step by step.
Key conversions to remember:
- 1 hour = 60 minutes
- 1 minute = 60 seconds
- 1 day = 24 hours
Let me work through each problem:
1. 9 hours 30 minutes = ___ minutes

- 420 + 45 = 465 seconds
3. 9 days 20 hours = ___ hours
- 9 days × 24 hours/day = 216 hours
- 216 + 20 = 236 hours
4. 10 minutes 27 seconds = ___ seconds
- 10 minutes × 60 seconds/minute = 600 seconds
- 600 + 27 = 627 seconds
5. 13 days 19 hours = ___ hours
- 13 days × 24 hours/day = 312 hours
- 312 + 19 = 331 hours
6. 6 hours 5 minutes = ___ minutes
