Question 792367: A cabinet maker builds 3 cabinets in 2 days. An apprecntice workes 1/2 as fast. How many days does it take the apprentice to make 9 cabinets?
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
The cabinet maker's rate of working is:
( 3 cabinets ) / ( 2 days )
-----------------------
If the apprentice works at half that rate,
his rate is:
( 3 cabinets ) / ( 4 days )
---------------------
How long will it take the apprentice to make
3 times as many cabinets?
It will takes 3 times as long, or
12 days
---------
In terms of just units,
( number of cabinets ) / ( rate in cabinets/days ) = days
