Bob takes 45 minutes each day for lunch. He does not get paid for the lunch break. How many hours does he work in a 5-day workweek if he checks in at 8:00 a.m. and checks out at 5:15 p.m. each day?
5:15+12:00 (the 12 hours is added because it is PM) - 8:00 (the time he starts, because you don't want to include the time for 8 AM for that day)- 0:45 (he doesn't get paid for lunch)=8:30 (time he works for one day)
5:15+12:00-8:00-0:45=8:30
8:30 or 8.5 hours * 5 days =42.5 hours
To calculate the number of hours Bob works in a 5-day workweek, we need to subtract the time he spends on his lunch break from the total working hours each day.
First, let's calculate the total working hours in a day. Bob checks in at 8:00 a.m. and checks out at 5:15 p.m. To calculate the time difference, we subtract the check-in time from the check-out time:
5:15 p.m. - 8:00 a.m. = 9 hours and 15 minutes
Next, we need to deduct Bob's lunch break time from the total working hours. Bob takes 45 minutes each day for lunch, which needs to be converted to hours:
45 minutes ÷ 60 = 0.75 hours
Finally, we subtract the lunch break time from the total working hours:
9 hours and 15 minutes - 0.75 hours = 8 hours and 30 minutes
So, Bob works 8 hours and 30 minutes each day. Multiply this by 5 (for a 5-day workweek) to find the total number of hours he works in a week:
8 hours and 30 minutes × 5 = 42 hours and 30 minutes
Therefore, Bob works for approximately 42 hours and 30 minutes in a 5-day workweek.
