Final answer:
Rafael was doing chores for a total of 2 hours and 26 minutes. This was calculated by subtracting the start time (7:48 a.m.) from the finish time (9:14 a.m.) and accounting for the difference in both hours and minutes.
Step-by-step explanation:
To calculate the total time Rafael was doing chores, we need to subtract the time he started from the time he finished. Rafael started his chores at 7:48 a.m. and finished at 9:14 a.m.
The following steps break down the process:
- First, we begin by comparing the hours. Rafael started at 7 a.m. and finished at 9 a.m., so there is a total of 2 full hours between these two times.
- Next, we look at the minutes. Since Rafael finished at 14 minutes past the hour, and he began at 48 minutes past the hour before, we need to take the difference between these two-minute counts. Starting at 48 minutes and getting to 60 minutes completes an hour, which is 12 minutes. From 60 minutes to 14 minutes is an additional 14 minutes. So in total, 26 minutes between 7:48 a.m. and 9:14 a.m. need to be accounted for outside of the full hours.
- To combine these, we add the full hours to the additional minutes which gives us 2 hours and 26 minutes. This is the total time Rafael spent doing chores.
So, Rafael was doing chores for 2 hours and 26 minutes.
