He is walking monday to friday from 9:15 to 5:15
that is 8 hours
Per day he is spending 45 minutes for lunch.
==> 8 hours - 45 minutes = 7 hours and 15 minutes.
Per day from monday to friday 7 hours and 15 minutes.
So, for 5 days 7 hours and 15 minutes multiplied by 5.
=> 36 hours and 15 minutes.
On saturday he is waling from 9 to 12.


If it is afternoon 12, then there wont be any lunch before
that. so only 3 hours.
36 hours and 15 minutes + 3 hours = 39 hours 15 minutes.

If that is 12 in the night, then 16 - 45 minuts lunch.
15 hours and 15 minutes.
Then it becomes 36:15 + 15:15 = 51:30
51 hours and 30 minutes
