Problem (2): Usha reached 4 hours and 55 minutes earlier than Balvinder for a meeting. If Balvinder reached the meeting at 05:35 AM, the time at which Usha reached at the meeting is _______

Solution:
- Balvinder reached at 05:35 AM.
- Usha reached 4 hours and 55 minutes earlier.
- Subtract 4 hours and 55 minutes from 05:35 AM:
- First, subtract 4 hours:
$$
05:35 \text{ AM} - 4 \text{ hours} = 01:35 \text{ AM}
$$
- Next, subtract 55 minutes:
$$
01:35 \text{ AM} - 55 \text{ minutes} = 00:40 \text{ AM}
$$
- Therefore, Usha reached at 00:40 AM.

Answer:
$$
\boxed{00:40}

- Add the additional 19 hours:
$$
72 + 19 = 91 \text{ hours}
$$

Answer:
$$
\boxed{91}
$$

#### (B) 9 days and 5 hours = _______ hours

$$
- From 12:00 PM to 2:10 PM:
$$
2:10 \text{ PM} - 12:00 \text{ PM} = 2 \text{ hours and } 10 \text{ minutes}
$$
- Total duration:
$$
1 \text{ hour and } 45 \text{ minutes} + 2 \text{ hours and } 10 \text{ minutes} = 3 \text{ hours and } 55 \text{ minutes}
$$

Answer:
$$
\boxed{3 \text{ hours and } 55 \text{ minutes}}

#### (A) 11 hours and 41 minutes = _______ seconds
Solution:
- 1 hour = 3600 seconds.
- 11 hours = $ 11 \times 3600 = 39600 $ seconds.
- 1 minute = 60 seconds.
- 41 minutes = $ 41 \times 60 = 2460 $ seconds.
- Total seconds:
$$
39600 + 2460 = 42060 \text{ seconds}
$$

Answer:
$$
\boxed{42060}
$$

#### (B) 11 hours and 39 minutes = _______ seconds
Solution:
- 1 hour = 3600 seconds.

- 39 minutes = $ 39 \times 60 = 2340 $ seconds.
- Total seconds:
$$
39600 + 2340 = 41940 \text{ seconds}
$$

Answer:
$$
\boxed{41940}
