It looks like you've uploaded an image of a completed worksheet titled
"Units of Time - Conversion" with an answer key. The worksheet contains 20 problems involving conversions between different units of time (seconds, minutes, hours, days, weeks), and all the answers are already filled in.
Since this is an
answer key, it appears to be a solution guide for students or teachers to check their work. Below, I’ll go through a few examples to
explain how each conversion works, so you can understand the logic behind the answers:
---
🔁 Key Conversion Rules:
- 1 minute = 60 seconds
- 1 hour = 60 minutes
- 1 day = 24 hours
- 1 week = 7 days
---
✔ Example Problems & Explanations:
#### ① 12 minutes = ? seconds
Answer: 720 seconds
→ Multiply by 60:
12 × 60 = 720 seconds ✔️
---
#### ② 6 days = ? hours
Answer: 144 hours
→ Multiply by 24:
6 × 24 = 144 hours ✔️
---
#### ③ 600 minutes = ? hours
Answer: 10 hours
→ Divide by 60:
600 ÷ 60 = 10 hours ✔️
---
#### ④ 5 days = ? minutes
Answer: 7200 minutes
→ First convert to hours: 5 × 24 = 120 hours
Then convert to minutes: 120 × 60 = 7200 minutes ✔️
---
#### ⑤ 1344 hours = ? weeks
Answer: 8 weeks
→ Convert hours → days: 1344 ÷ 24 = 56 days
Then days → weeks: 56 ÷ 7 = 8 weeks ✔️
---
#### ⑥ 9 hours = ? minutes
Answer: 540 minutes
→ 9 × 60 = 540 ✔️
---
#### ⑦ 17 weeks = ? days
Answer: 119 days
→ 17 × 7 = 119 ✔️
---
#### ⑧ 600 hours = ? days
Answer: 25 days
→ 600 ÷ 24 = 25 ✔️
---
#### ⑨ 5 weeks = ? hours
Answer: 840 hours
→ 5 × 7 = 35 days
→ 35 × 24 = 840 hours ✔️
---
#### ⑩ 4 minutes = ? seconds
Answer: 240 seconds
→ 4 × 60 = 240 ✔️
---
#### ⑪ 18 hours = ? minutes
Answer: 1080 minutes
→ 18 × 60 = 1080 ✔️
---
#### ⑫ 18 weeks = ? days
Answer: 126 days
→ 18 × 7 = 126 ✔️
---
#### ⑬ 300 hours = ? days
Answer: 12.5 days
→ 300 ÷ 24 = 12.5 ✔️
---
#### ⑭ 7 weeks = ? hours
Answer: 1176 hours
→ 7 × 7 = 49 days
→ 49 × 24 = 1176 ✔️
---
#### ⑮ 17 minutes = ? seconds
Answer: 1020 seconds
→ 17 × 60 = 1020 ✔️
---
#### ⑯ 10 days = ? hours
Answer: 240 hours
→ 10 × 24 = 240 ✔️
---
#### ⑰ 480 minutes = ? hours
Answer: 8 hours
→ 480 ÷ 60 = 8 ✔️
---
#### ⑱ 2 days = ? minutes
Answer: 2880 minutes
→ 2 × 24 = 48 hours
→ 48 × 60 = 2880 ✔️
---
#### ⑲ 2352 hours = ? weeks
Answer: 14 weeks
→ 2352 ÷ 24 = 98 days
→ 98 ÷ 7 = 14 weeks ✔️
---
#### ⑳ 17 hours = ? minutes
Answer: 1020 minutes
→ 17 × 60 = 1020 ✔️
---
✔ Summary:
All answers on the worksheet are
correct and follow standard time conversion rules. This worksheet helps students practice converting between:
