3 men take 6 hrs to paint 1 house
-------------------------------
Twice as many men can paint
1 house in half that time, so
------------------------------
6 men take 3 hrs to paint 1 house
------------------------------
One third that number of men will take
3 times as long to paint 1 house, so
---------------------------------
2 men take 9 hrs to paint 1 house
