A cat eats nine sausages in 30 minutes. A dog can eat the same number of sausages in 2/3 the amount of time the cat takes. Calculate the average time the two take the eat the sausages.
If the cat takes 30 minutes to eat the sausages, the dog takes 2/3*30 = <<30*2/3=20>>20 minutes.
The total amount of time the cat and the dog take to eat the sausages is 20+30 = <<20+30=50>>50 minutes.
The average time in minutes that the two take to eat the sausages is 50/2 = <<50/2=25>>25 minutes.
