Final answer:
The length of the interval between 0930 (9:30 AM) and 1345 (1:45 PM) is 4 hours and 15 minutes.
Step-by-step explanation:
To find the length of the interval between 0930 (9:30 AM) and 1345 (1:45 PM), we need to calculate the difference in time.
First, convert 1345 to a 24-hour format which is already in the correct format - 1:45 PM. Subtract the start time (0930 or 9:30 AM) from the end time (1345 or 1:45 PM).
1:45 PM is the same as 13:45 in 24-hour format. Now subtract the hours and then the minutes separately.
- 13 hours - 9 hours = 4 hours
- 45 minutes - 30 minutes = 15 minutes
Combine the hours and minutes to get the total interval length, which is 4 hours and 15 minutes.
