Describe two different methods to find the elapsed time from 2: 30pm to 2: 58pm

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.
