A)6.83

B)5.22

C)5.83

D)6.00

Answer 1

35 minutes / 6 dispensers per minute = 5.83 minutes per dispenser 

Answer 2

You can set up a proportion if you like and cross multiply:

 

35    =    x

---         ---

6            1 

 

(35) (1)  =  (6)(x)

35  = 6x

35/6 = 6x/6

5.83 = x

 

 

 

Or simply divide 35/6 gives us 5.83
