Sagot :
Answer:
Hence, beginning time is:
9:38 a.m.
Step-by-step explanation:
We know that:
" Elapsed time is the time or difference between a beginning time and an ending time "
Here we are given that the ending time is:
10:08 a.m.
and elapsed time is:
0:30 minutes.
This means the beginning time will be :
ending time - elapsed time.
Hence on counting back 30 minutes from 10:08 am we get the beginning time as:
9:38 a.m.
We have to subtract 30 minutes from 10:08 am, then the elapsed time will be 9 hours 38 minutes.
What is subtraction?
It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.
Ending time: 10:08 am elapsed time: 30 minutes. Then the time will be
We know that elapsed means before 10:08 am. So we have to subtract 30 minutes from 10:08 am. Then we have
[tex]\begin{matrix} & 10 & : & 08 \\- & 00 & : & 30 \\& \overline{09} & : & \overline{38}\end{matrix}\\[/tex]
Then the time will be 09:38 am.
