Five maids can clean seven houses in three days. How long would it take eight maids to clean twenty houses if all the work was done at the same rate?
-------
time is indirectly related to # of maids and directly related to # of houses:
t = k*h/m
-------
Solve for "k" using "Five maids can clean seven houses in three days".
--------------------
3 = k*7/5
k = 15/7
=========
Equation:
t = (15/7)h/m
=====
How long would it take eight maids to clean twenty houses if all the work was done at the same rate?
t = (15/7)*20/8
-----------
t = 300/56
t = 5.36 days
