To calculate the total hours worked:

1. The shift starts at 22:00 (10:00 PM) and ends at 06:00 (6:00 AM). The time from 22:00 to midnight (24:00) is 2 hours. Then, from midnight to 06:00 is 6 hours. So, the total shift length is:

$2 \text{ hours} + 6 \text{ hours} = 8 \text{ hours}$

2. Subtract the 45-minute break (which is 0.75 hours) from the total shift length:

$8 \text{ hours} - 0.75 \text{ hours} = 7.25 \text{ hours}$

Therefore, you work 7.25 hours during your shift.

Here are 5 related questions:

1. How do you calculate overtime if you worked beyond 06:00?
2. How would the total hours change if your break was 30 minutes instead of 45 minutes?
3. What if your shift started at 21:00 instead of 22:00? How many hours would you work then?
4. How does the calculation change if you take two breaks instead of one?
5. If your shift lasted 10 hours with a 1-hour break, how many hours would you work?

Tip: Converting minutes into decimal hours can simplify time calculations (e.g., 45 minutes = 0.75 hours).
