The elapsed time typically refers to the amount of time spent from the beginning of an event to the end of such event. Now id we have a time line; that shows 9:00; then if we count backward 5 minutes ; we have 55 more minutes for an hour to run out. Then we then count another 1 more minutes, leaving us with 54 minutes. The 54 minutes remaining is said to be our total elapsed time.
i.e 9:00 - (5 + 1) minutes
8:54 (8 hours 54 minutes)
Hence; 54 minutes remaining is said to be our total elapsed time.
