<PRE><B>Question 994654</B>
if it takes 2 ppl 9 hours to paint a fence and 3 ppl 6 hours to paint a fence. how many would it take 1 person 
----
# of people and # of hours are inversely related::
t = k/n
----
Solve for &quot;k&quot; using 2ppl take 9 hrs::
9 = k/2
k = 18
-----
? How long would it take one person?
t = 18/n
time = 18/1 = 18 hours
