------
# of cats is directly related to # of mice and indirectly related to time
-------
c = k*m/t
------------
Solve for "k" using "3 cats catch 3 mice in 3 minutes"::
3 = k*3/3
----
k = 3
------
Equation::
c = 3(m/t)
--------
how many cats are needed to catch 60 mice in one hour?
c = 3(60/60)
----
c = 3 (# of cats needed)
