Numeracy question. You start night shift at 22:00 and finish at 06:00 with a 45-minute break. How many hours do you work?
You start night shift at 22:00 and finish at 06:00 with a 45-minute break. How many hours do you work?

To calculate the total hours worked, we start by determining the total time from the beginning to the end of the shift and then subtract the break time.

1. **Total Time of the Shift:**
   - Start time: 22:00 (10:00 PM)
   - End time: 06:00 (6:00 AM next day)

   From 22:00 to midnight is 2 hours, and from midnight to 06:00 is 6 hours. So, the total shift time is:

   \[
   2 \, \text{hours} + 6 \, \text{hours} = 8 \, \text{hours}
   \]

2. **Subtract the Break Time:**
   - Break time: 45 minutes, which is 0.75 hours.

   So, the total working time is:

   \[
   8 \, \text{hours} - 0.75 \, \text{hours} = 7.25 \, \text{hours}
   \]

Therefore, you work **7 hours and 15 minutes**.
