Answer:
We know that:
" Elapsed time is the time or difference between a beginning time and an ending time ".
Now the two different methods to find the elapsed time is:
Method 1:
Subtract 2:30 directly from 2:58.
2:58 - 2:30 = 0:28
Hence, the elapsed time is 28 minutes.
Method 2:
Round 2:58 to 3:00, subtract 2:30 from 3:00, and at the end subtract 2 to get the desired time(2:58 + 2 = 3:00)
( Since it is easy to calculate the whole numbers).
2:58 is approximately 3:00
3:00 - 2:30 = 30 min
30 min - 2 min = 28 min.
Hence, elapsed times is 28 minutes.
