Final answer:
The time between 7:45 am today and 3:15 pm tomorrow is 31 hours and 30 minutes, calculated by adding the time from 7:45 am to midnight with the time from midnight to 3:15 pm the following day.
Step-by-step explanation:
To find out how much time there is between 7:45 am today and 3:15 pm tomorrow, first, we calculate the time from 7:45 am to midnight, and then from midnight to 3:15 pm the following day.
From 7:45 am to 12:00 pm (midnight) is 16 hours and 15 minutes. This is because there are 4 hours and 15 minutes from 7:45 am to 12:00 pm (noon), and then an additional 12 hours from noon to midnight. Now, from midnight to 3:15 pm the following day is 15 hours and 15 minutes. Adding these two amounts together:
- 16 hours and 15 minutes (from 7:45 am to midnight)
- 15 hours and 15 minutes (from midnight to 3:15 pm the next day)
16 hours and 15 minutes + 15 hours and 15 minutes = 31 hours and 30 minutes. So, the time between 7:45 am today and 3:15 pm tomorrow is 31 hours and 30 minutes.
