Answer:
7 hours 45 minutes
Step-by-step explanation:
If Tommy started work at 7 a.m. and left at 2:45 p.m
To find out the record time for the day , subtract the time left from the time started.
[tex]2.45 pm - 7 am[/tex]
The difference between 7 am and 2 pm is 7 hours
Now we add the extra 45 minutes
So the time record for the day is 7 hours 45 minutes
