You can put this solution on YOUR website! x people take w hours to paint a house. How long would it take y people to paint the same house?
----------------
The variables are indirectly related:
So, time = k/number
Find k:
w = k/x
k = xw
--------------
General Equation:
time = (xw)/number
----------
for y people the time would be:
time for y people to do the job = (xw)/y
