Calculate the elapsed time between:
11:15 A.M. and 6:00 P.M.
Review AM and PM values:
Time crossed over from A.M. to P.M.
Find the difference between 12 and our hour on each side of the A.M. P.M. dividing line
The minute of 6:00 P.M. is less than the minute of 11:15 A.M.
Borrow 1 hour from the hour reading which is 60 minutes
Add this to the minutes calculation
Answer in Hours = (12 - 11) + 6 - 1 borrowed hour
Answer in Hours = 1 + 6 - 1 = 6
Answer in Minutes = 60 - 15 + 00 = 45
Final Answer
Elapsed Time = 6 hours and 45 minutes
