What is the elapsed time? 1 Hour and 40 Minutes.

Explanation why your answer is correct: ?

Right.

I subtracted 12 hours - 4 hours = 8 hours. I also subtracted 50 minutes - 5 minutes = 45 minutes. And gave me the elapsed time of 8 hours and 45 minutes.

To find the elapsed time, we need to subtract the starting time from the ending time. In this case, the starting time is 4:05 p.m. and the ending time is 5:45 p.m.

First, we need to convert both times into a standardized format. 4:05 p.m. can be written as 16:05 in 24-hour format, and 5:45 p.m. can be written as 17:45 in 24-hour format.

Next, we subtract the starting time from the ending time:

17:45 - 16:05 = 1:40

So, the elapsed time is 1 hour and 40 minutes.
