Lots of points!!!

Byron can fill a drying rack with dishes in 15 minutes. While Byron fills the drying rack, Emmitt takes dishes out of the drying rack and puts them in bins. With Emmitt taking dishes out of the drying rack, it takes 35 minutes for Byron to fill the drying rack.

Which of the following can be used to determine the amount of time it takes for Emmitt to empty the drying rack if Byron is not adding dishes?
A.) 


B.) 
C.)   
D.)

Answer 1

You would do 35 - 15 = 20 because if it takes 35 minutes to do both just take away how long it took to fill it :) hope i helped and got what you were looking for. so your answer is (20)

Answer 2

B.) (1/15)- (1/x) = (1/35)
B would be the answer because 35-15=20 so b can be used to determine the amount of time it takes for Emmitt to empty the drying rack if Byron is not adding dishes.
