Answer 1

Answer :-

Given that

Start :- 8:20 am

Lunch :- 12:00 pm

Back :- 12:45 pm

End :- 5:00 pm

Now

Total time between start and end

= 8:20 am to 5:00 pm

= 8 hours and 40 min (17 :00 - 8:20 )

now the time he took rest (lunch)

12:00 to 12:45

= 45 min

as he was not working during the lunch time so we will subtract it from total time between start and end

= 8 hrs and 40 min - 45 min

= 7 hours and 55 min

so he worked for

7 hours and 55 min

Answer:

7 hrs 55 min

Step-by-step explanation:

3 hrs 40 min ( between start and lunch ) + 4 hrs 15 min ( between back and end )

= 7 hrs 55 min
