Calculate the time lapse for each given start and end time.

Here are the time lapses for each entry:

1) Start Time: 1:00 am, End Time: 3:15 am $3 hours 15 minutes - 1 hour 0 minutes = \text{2 hours 15 minutes}$

2) Start Time: 5:30 am, End Time: 12:12 pm Step 1: Calculate time from 5:30 am to 12:00 pm. $12 hours 0 minutes - 5 hours 30 minutes = 6 hours 30 \text{ minutes}$ Step 2: Add time from 12:00 pm to 12:12 pm. $6 hours 30 minutes + 12 minutes = \text{6 hours 42 minutes}$

3) Start Time: 4:30 am, End Time: 4:30 pm Step 1: Convert 4:30 pm to 24-hour format, which is 16:30. Step 2: Subtract the start time from the end time. $16 hours 30 minutes - 4 hours 30 minutes = \text{12 hours 0 minutes}$

4) Start Time: 7:45 pm, End Time: 8:52 pm Step 1: Convert times to 24-hour format: 7:45 pm is 19:45, 8:52 pm is 20:52. Step 2: Subtract the start time from the end time. $20 hours 52 minutes - 19 hours 45 minutes = \text{1 hour 7 minutes}$

5) Start Time: 11:30 pm, End Time: 10:20 am Step 1: Calculate time from 11:30 pm to 12:00 am (midnight). $12 hours 0 minutes - 11 hours 30 minutes = 30 \text{ minutes}$ Step 2: Calculate time from 12:00 am to 10:20 am. $10 hours 20 \text{ minutes}$ Step 3: Add the durations from Step 1 and Step 2. $30 minutes + 10 hours 20 minutes = \text{10 hours 50 minutes}$
