Let’s go through each problem one by one. We’ll start with a time on the first clock, then add the minutes shown (10, 20, or 30) to get the time on the second clock.
We can pick any starting time — let’s use
1:00 for all of them to keep it simple and consistent. You can choose your own starting time too, as long as you add the correct number of minutes!
---
Problem 1: 10 minutes apart
Start at 1:00 → Add 10 minutes → 1:10
So: First clock = 1:00, Second clock = 1:10
Problem 2: 10 minutes apart
Start at 1:00 → Add 10 minutes → 1:10
First clock = 1:00, Second clock = 1:10
Problem 3: 20 minutes apart
Start at 1:00 → Add 20 minutes → 1:20
First clock = 1:00, Second clock = 1:20
Problem 4: 20 minutes apart
Start at 1:00 → Add 20 minutes → 1:20
First clock = 1:00, Second clock = 1:20
Problem 5: 30 minutes apart
Start at 1:00 → Add 30 minutes → 1:30
First clock = 1:00, Second clock = 1:30
Problem 6: 30 minutes apart
Start at 1:00 → Add 30 minutes → 1:30
First clock = 1:00, Second clock = 1:30
Problem 7: 10 minutes apart
Start at 1:00 → Add 10 minutes → 1:10
First clock = 1:00, Second clock = 1:10
Problem 8: 20 minutes apart
Start at 1:00 → Add 20 minutes → 1:20
First clock = 1:00, Second clock = 1:20
Problem 9: 30 minutes apart
Start at 1:00 → Add 30 minutes → 1:30
First clock = 1:00, Second clock = 1:30
Problem 10: 30 minutes apart
Start at 1:00 → Add 30 minutes → 1:30
First clock = 1:00, Second clock = 1:30

✔ All answers are based on starting at 1:00 and adding the required minutes. You could also start at other times like 2:00 or 3:00 — just make sure you add the right amount!
Final Answer:
For each pair of clocks, set the first clock to any time (e.g., 1:00), then set the second clock to that time plus the minutes shown (10, 20, or 30). Example using 1:00:
1. 1:00 → 1:10
2. 1:00 → 1:10
3. 1:00 → 1:20
4. 1:00 → 1:20
5. 1:00 → 1:30
6. 1:00 → 1:30
7. 1:00 → 1:10
8. 1:00 → 1:20
9. 1:00 → 1:30
10. 1:00 → 1:30
