Simone has 5 employees in her flower shop. each employee works
6 4/15 hours per day. how many hours, in total, do the 5 employees work per day?
a. 30 2/3
b. 28
c. 31 1/3
d. 30

Total number of employees = 5
Time spend by each employee = 6 4/15
                                            = 6 (4/15*60)   
                                            = 6 hrs (4*4  minutes)
                                            = 6 hrs 16 minutes
                                            = 360+16 minutes
                                            = 376 minutes
                                            
Time spend by 5 employees =  5* 376
                                              = 1880 minutes

We should find answer in hours 
Therefore , time spend = 1880/60
                                     = 94/3
                                     = 31 1/3 hrs

Therefore, time spend by 5 employees is 31 1/3 hrs
