Adding Minutes worksheet with analog clocks and time-related questions.

Problem: Adding Minutes to Time

The task involves reading the time on each clock and performing addition or subtraction of minutes to determine the resulting times. Let's solve this step by step for each clock.

---

#### Clock 1:
- Current Time: The hour hand is between 2 and 3, and the minute hand is on 5. This indicates 2:25.

1. What time will it be in 55 minutes?
- Start with 2:25.
- Add 55 minutes:
- 2:25 + 55 minutes = 2:80 (since 25 + 55 = 80).
- Convert 80 minutes to hours and minutes: 80 minutes = 1 hour and 20 minutes.
- Add 1 hour to 2:00 → 3:00, then add the remaining 20 minutes → 3:20.

2. What time will it be in 100 minutes?
- Start with 2:25.
- Add 100 minutes:
- 2:25 + 100 minutes = 2:125 (since 25 + 100 = 125).
- Convert 125 minutes to hours and minutes: 125 minutes = 2 hours and 5 minutes.
- Add 2 hours to 2:00 → 4:00, then add the remaining 5 minutes → 4:05.

3. What time was it 50 minutes ago?
- Start with 2:25.
- Subtract 50 minutes:
- 2:25 - 50 minutes = 2:-25 (since 25 - 50 = -25).
- Convert -25 minutes to the previous hour: 1 hour and 35 minutes before 2:00 → 1:35.

#### Clock 2:
- Current Time: The hour hand is between 1 and 2, and the minute hand is on 10. This indicates 1:10.

1. What time will it be in 90 minutes?
- Start with 1:10.
- Add 90 minutes:
- 1:10 + 90 minutes = 1:100 (since 10 + 90 = 100).
- Convert 100 minutes to hours and minutes: 100 minutes = 1 hour and 40 minutes.
- Add 1 hour to 1:00 → 2:00, then add the remaining 40 minutes → 2:40.

2. What time will it be in 125 minutes?
- Start with 1:10.
- Add 125 minutes:
- 1:10 + 125 minutes = 1:135 (since 10 + 125 = 135).
- Convert 135 minutes to hours and minutes: 135 minutes = 2 hours and 15 minutes.
- Add 2 hours to 1:00 → 3:00, then add the remaining 15 minutes → 3:15.

3. What time was it 70 minutes ago?
- Start with 1:10.
- Subtract 70 minutes:
- 1:10 - 70 minutes = 1:-60 (since 10 - 70 = -60).
- Convert -60 minutes to the previous hour: 1 hour before 1:00 → 12:10.

#### Clock 3:
- Current Time: The hour hand is between 3 and 4, and the minute hand is on 2. This indicates 3:10.

1. What time will it be in 75 minutes?
- Start with 3:10.
- Add 75 minutes:
- 3:10 + 75 minutes = 3:85 (since 10 + 75 = 85).
- Convert 85 minutes to hours and minutes: 85 minutes = 1 hour and 25 minutes.
- Add 1 hour to 3:00 → 4:00, then add the remaining 25 minutes → 4:25.

2. What time will it be in 100 minutes?
- Start with 3:10.
- Add 100 minutes:
- 3:10 + 100 minutes = 3:110 (since 10 + 100 = 110).
- Convert 110 minutes to hours and minutes: 110 minutes = 1 hour and 50 minutes.
- Add 1 hour to 3:00 → 4:00, then add the remaining 50 minutes → 4:50.

3. What time was it 32 minutes ago?
- Start with 3:10.
- Subtract 32 minutes:
- 3:10 - 32 minutes = 2:38 (since 10 - 32 = -22, which is 22 minutes before 3:00 → 2:38).

#### Clock 4:
- Current Time: The hour hand is between 7 and 8, and the minute hand is on 7. This indicates 7:35.

1. What time will it be in 47 minutes?
- Start with 7:35.
- Add 47 minutes:
- 7:35 + 47 minutes = 7:82 (since 35 + 47 = 82).
- Convert 82 minutes to hours and minutes: 82 minutes = 1 hour and 22 minutes.
- Add 1 hour to 7:00 → 8:00, then add the remaining 22 minutes → 8:22.

2. What time will it be in 123 minutes?
- Start with 7:35.
- Add 123 minutes:
- 7:35 + 123 minutes = 7:158 (since 35 + 123 = 158).
- Convert 158 minutes to hours and minutes: 158 minutes = 2 hours and 38 minutes.
- Add 2 hours to 7:00 → 9:00, then add the remaining 38 minutes → 9:38.

3. What time was it 99 minutes ago?
- Start with 7:35.
- Subtract 99 minutes:
- 7:35 - 99 minutes = 6:96 (since 35 - 99 = -64, which is 64 minutes before 7:00 → 6:96).
- Convert -64 minutes to the previous hour: 1 hour and 26 minutes before 7:00 → 6:26.
