on average, how many cups of coffee does each person at the firm drink per hour, assuming a 10-hour work day?

A person drinks 4.52 cups per hour

Step-by-step explanation:  

No of work days = 5

No of hours in day = 10

No of hours in week = 10*5= 50 hours

Total cups consumed = 226

No of cups consumed per hour = Total no of cups/ Total week  hours            

                                                     = 226/50

                                                     = 4.52 cups/ hour
