Eight
7:30 + 0:30 = 8:00
4pm = 16:00 hours
16 - 8 = 8
That would be 10 hours, when you exclude the 30 minute break.
If you are asking how to break down 9.6 hours into hours and min. then the answer 9 hours and 36 min.
It depends on the state and how often you get a break. Most states require a 15 min break every 6 hours.
9 to 5 is 8 hours. If you subtract the lunch break, you get 7 hours, 30 minutes.
Anyone who works about 6 - 12 hours a day should have a min of 30 min break which in most cases is divided by two. (that will make two 15 min breaks in 6-12h period) Big companies will give you an hour lunch (that might not be paid by the employer) plus one or two 15 min breaks. It all depends where you work, but the minimum time limit for break/s for 8 hours of work is 30 min.
0 hours are in 20 min an hour is 60 min
8 hours, 20 minutes
610 min / 60 = 10.167 hours.
2 hours
5 hours, 50 minutes
60 min = 1 hour so 375 min = 6 hours 15 minutes.
320 min = 51/3 hours = 5hours 20minutes
