Let’s solve each problem step by step. We’ll convert larger time units into smaller ones using these facts:
- 1 hour = 60 minutes
- 1 minute = 60 seconds
- 1 day = 24 hours
---
1. 9 hours 30 minutes = ? minutes
→ 9 hours × 60 = 540 minutes
→ Add 30 minutes → 540 + 30 =
570 minutes
---
2. 7 minutes 45 seconds = ? seconds
→ 7 minutes × 60 = 420 seconds
→ Add 45 seconds → 420 + 45 =
465 seconds
---
3. 9 days 20 hours = ? hours
→ 9 days × 24 = 216 hours
→ Add 20 hours → 216 + 20 =
236 hours
---
4. 10 minutes 27 seconds = ? seconds
→ 10 minutes × 60 = 600 seconds
→ Add 27 seconds → 600 + 27 =
627 seconds
---
5. 13 days 19 hours = ? hours
→ 13 days × 24 = 312 hours
→ Add 19 hours → 312 + 19 =
331 hours
---
6. 6 hours 5 minutes = ? minutes
→ 6 hours × 60 = 360 minutes
→ Add 5 minutes → 360 + 5 =
365 minutes
---
7. 10 hours 30 minutes = ? minutes
→ 10 hours × 60 = 600 minutes
→ Add 30 minutes → 600 + 30 =
630 minutes
---
8. 6 minutes 15 seconds = ? seconds
→ 6 minutes × 60 = 360 seconds
→ Add 15 seconds → 360 + 15 =
375 seconds
---
9. 4 days 20 hours = ? hours
→ 4 days × 24 = 96 hours
→ Add 20 hours → 96 + 20 =
116 hours
---
10. 3 minutes 45 seconds = ? seconds
→ 3 minutes × 60 = 180 seconds
→ Add 45 seconds → 180 + 45 =
225 seconds
---
11. 20 days 21 hours = ? hours
→ 20 days × 24 = 480 hours
→ Add 21 hours → 480 + 21 =
501 hours
---
12. 12 hours 5 minutes = ? minutes
→ 12 hours × 60 = 720 minutes
→ Add 5 minutes → 720 + 5 =
725 minutes
---
Final Answer:
570, 465, 236, 627, 331, 365, 630, 375, 116, 225, 501, 725
