Explanation:
Let’s solve each part step by step.
Part 1: Reading analogue clocks
We need to read each clock and write the time in both 12-hour and 24-hour formats.
-
First clock (In the morning):
Hour hand is between 3 and 4 → it’s 3 o’clock.
Minute hand points at 9 → 9 × 5 = 45 minutes.
So time = 3:45 AM.
In 12-hour format:
3:45 a.m.
In 24-hour format:
03:45
-
Second clock (In the evening):
Hour hand is between 11 and 12 → it’s 11 o’clock.
Minute hand points at 7 → 7 × 5 = 35 minutes.
So time = 11:35 PM.
In 12-hour format:
11:35 p.m.
In 24-hour format: 11 + 12 =
23:35
-
Third clock (In the afternoon):
Roman numerals: hour hand is just past V (5), minute hand at VIII (8) → 8 × 5 = 40 minutes.
So time = 5:40 PM.
In 12-hour format:
5:40 p.m.
In 24-hour format: 5 + 12 =
17:40
-
Fourth clock (In the early morning):
Hour hand near 12, minute hand at 5 → 5 × 5 = 25 minutes.
So time = 12:25 AM.
In 12-hour format:
12:25 a.m.
In 24-hour format:
00:25 (since midnight is 00:00, 12:25 a.m. is 00:25)
✔ Double-check: Yes — 12:25 a.m. is before 1 a.m., so 24-hour is 00:25.

Part 2: Time conversions
Use the facts:
- 1 hour = 60 minutes
- 1 day = 24 hours
- 1 year = 12 months
a.
Minutes
- 3 hours = 3 × 60 =
180 minutes (already given)
- 2 hours = 2 × 60 =
120 minutes
- 10 hours = 10 × 60 =
600 minutes
b.
Hours
- 10 days = 10 × 24 =
240 hours
- 120 minutes = 120 ÷ 60 =
2 hours
- 3 days = 3 × 24 =
72 hours
c.
Months
- 3 years = 3 × 12 =
36 months
- 10 years = 10 × 12 =
120 months
- 5 years = 5 × 12 =
60 months
All calculations checked.
Final Answer:
1.
- In the morning: 3:45 a.m., 03:45
- In the evening: 11:35 p.m., 23:35
- In the afternoon: 5:40 p.m., 17:40
- In the early morning: 12:25 a.m., 00:25
2.
a. 2 hours = 120 minutes; 10 hours = 600 minutes
b. 10 days = 240 hours; 120 minutes = 2 hours; 3 days = 72 hours
c. 3 years = 36 months; 10 years = 120 months; 5 years = 60 months
