8 and 5/6 hours
To calculate the time from 8:30 AM to 5:50 PM, first find the difference in hours and minutes. From 8:30 AM to 5:30 PM is 9 hours, and then from 5:30 PM to 5:50 PM is an additional 20 minutes. Therefore, the total time from 8:30 AM to 5:50 PM is 9 hours and 20 minutes.
From 11:30 AM to 5:50 PM is a total of 6 hours and 20 minutes. To break it down, there are 6 hours from 11:30 AM to 5:30 PM, and then an additional 20 minutes to reach 5:50 PM.
There are 3 hours between 12:30 pm and 3:30 pm.
The time from 2:30 PM to 9:30 PM is a total of 7 hours. This can be calculated by counting the hours from 2:30 PM to 9:30 PM, which includes 3 hours to reach 5:30 PM and an additional 4 hours to reach 9:30 PM.
From 10:30 AM to 4:30 PM is a total of 6 hours. You can calculate this by counting the hours from 10:30 AM to 4:30 PM, which includes 11:30 AM, 12:30 PM, 1:30 PM, 2:30 PM, 3:30 PM, and finally 4:30 PM. Therefore, the duration is 6 hours.
To calculate the hours from 9:20 AM to 5:50 PM, first find the total time without lunch: from 9:20 AM to 5:50 PM is 8 hours and 30 minutes. Subtracting the 30-minute lunch break gives you a total of 8 hours. Therefore, the total working hours are 8 hours.
7 hours 30 minutes.
From 1:30 PM to 10:00 PM is 8 hours and 30 minutes. To calculate, you can count the hours from 1:30 PM to 10:00 PM, which includes the full hours from 2 PM to 10 PM (8 hours) plus the additional 30 minutes from 1:30 PM to 2 PM.
There are 3 hours and 50 minutes between 11:30 am and 3:20 pm.
7 hours and 30 minutes
From 12 PM to 10:30 PM is a duration of 10 hours and 30 minutes. This can be calculated by counting the hours from 12 PM to 10 PM (which is 10 hours) and then adding the additional 30 minutes.
The duration from 8:30 AM to 3:30 PM is 7 hours. To break it down, from 8:30 AM to 12:30 PM is 4 hours, and from 12:30 PM to 3:30 PM is an additional 3 hours. Therefore, the total time is 4 hours plus 3 hours, equaling 7 hours.
