Let’s solve each problem one by one. We’ll look at the clock shown, then add or subtract the time given to find what time it was or will be.

Problem 1:
Clock shows: 4:25
Question: What time was it 1 hour 38 minutes ago?
Step 1: Subtract 1 hour from 4:25 → 3:25
Step 2: Now subtract 38 minutes from 3:25
→ 3:25 minus 25 minutes = 3:00
→ Still need to subtract 13 more minutes (because 38 - 25 = 13)
→ 3:00 minus 13 minutes = 2:47
✔ Answer for #1:
2:47

Problem 2:
Clock shows: 9:50
Question: What time was it 2 hours 14 minutes ago?
Step 1: Subtract 2 hours from 9:50 → 7:50
Step 2: Subtract 14 minutes from 7:50
→ 7:50 minus 10 minutes = 7:40
→ Minus 4 more minutes = 7:36
✔ Answer for #2:
7:36

Problem 3:
Clock shows: 9:50 (same as #2)
Question: What time was it 2 hours 15 minutes ago?
Step 1: Subtract 2 hours → 7:50
Step 2: Subtract 15 minutes from 7:50
→ 7:50 minus 10 = 7:40
→ Minus 5 more = 7:35
✔ Answer for #3:
7:35

Problem 4:
Clock shows: 10:05
Question: What time will it be in 3 hours 5 minutes?
Step 1: Add 3 hours to 10:05 → 1:05 (next day? No — just 1 PM if we’re using 12-hour, but since clocks show 1–12, we go to 1:05)
Wait — actually, 10 + 3 = 13 → which is 1:00 on a 12-hour clock. So 10:05 + 3 hours = 1:05
Step 2: Add 5 minutes → 1:10
✔ Answer for #4:
1:10
*(Note: Since these are analog clocks showing 1–12, we assume 12-hour format without AM/PM. So 10:05 + 3h5m = 1:10)*

Problem 5:
Clock shows: 11:55
Question: What time will it be in 5 hours 24 minutes?
Step 1: Add 5 hours to 11:55 → 11 + 5 = 16 → 4:00 (since 16 - 12 = 4)
But wait — let’s do it carefully:
11:55 + 5 hours = 4:55 (because 11 + 5 = 16 → 4 o’clock, same minute)
Step 2: Add 24 minutes to 4:55
→ 4:55 + 5 minutes = 5:00
→ Still need to add 19 more minutes (24 - 5 = 19)
→ 5:00 + 19 minutes = 5:19
✔ Answer for #5:
5:19

Problem 6:
Clock shows: 6:00
Question: What time will it be in 5 hours 58 minutes?
Step 1: Add 5 hours to 6:00 → 11:00
Step 2: Add 58 minutes to 11:00
→ 11:00 + 58 minutes = 11:58
✔ Answer for #6:
11:58

Final Answer:
1. 2:47
2. 7:36
3. 7:35
4. 1:10
5. 5:19
6. 11:58
