9 hours and 34 minutes.
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.
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
Well, if it's from AM to PM (or also PM to AM), the answer would be 10 hours. However, if this is from AM to AM (or also PM to PM), then it would be 22 hours.
There are 2 hours between 1:30 PM and 3:30 PM. If you count from 1:30 PM to 2:30 PM, that's one hour, and then from 2:30 PM to 3:30 PM, that's another hour. So, the total is 2 hours.
