I do it in two parts. I calculate how much time has elapsed between the AM and noon, then how much time has elapsed between noon and the PM, then add them together.
There are 6 hours of elapsed time between 9:00 AM and 3:00 PM.
About 30 minutes
3 hours 53 minutes
The elapsed time of 1 pm to 9 am is 20 hours.
If you set a timing clock to zero at 9-00pm on Wednesday, by midnight it will have recorded 3-00 hours; we have reached the time which changes from the end of Wednesday to the beginning of Thursday; from there to 1-00am is only 1 hour, so altogether the elapsed time will be exactly 4-00 hours.

There are 6 hours of elapsed time between 9:00 AM and 3:00 PM.
1 hour and 40 minutes.
10:20
6 hours.
3 hours, 32 minutes
Between 1:30pm and 4:45pm there are 195 minutes .
The answer is 6 hours.
594 minutes.
899 minutes
There are 15 hours and 15 minutes between 5:15 am and 8:30 pm.
To calculate the time elapsed from 11:24 AM to 2:47 PM, first, find the difference in hours and minutes. From 11:24 AM to 12:00 PM is 36 minutes. Then, from 12:00 PM to 2:00 PM is 2 hours, and from 2:00 PM to 2:47 PM is an additional 47 minutes. Adding these together gives a total of 2 hours and 23 minutes elapsed.
