Question 781554
if 2 painters paint 2 rooms in 2 hours then how many painters will be required to paint 18rooms in 6hours 
-------
# of painters is directly related to # of rooms and inversely 
related to # of hours.
----
p = k*r/h
-----
Solve for "k" using "2 painters paint 2 rooms in 2 hours"::
2 = k*2/2
---
k = 2
------
p = 2*r/h
------
Solve:: "how many painters will be required to paint 18 rooms in 6hours".
p = 2*18/6
---
p = 6 (# of painters required)
