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.
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.
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.
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.
There are 3 hours and 50 minutes between 11:30 am and 3:20 pm.
7 hours and 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.
From 8:30 AM to 7:30 PM is a total of 11 hours. You can calculate this by counting the hours from 8:30 AM to 12:00 PM (3.5 hours) and then from 12:00 PM to 7:30 PM (7.5 hours), which adds up to 11 hours.
8:30 AM to 1 PM = 4.5 hours 8:30 PM to 1 PM = 16.5 hours
