it takes 3 men 8 hours to build 10 sheds. How many hours will it take 9 men to build 15 sheds?
-----
time is inversely related to # of men and directly related to # of sheds
00000
t = k*s/m
----
Solve for "k" using "it takes 3 men 8 hours to build 10 sheds"
8 = k*10/3
k = 2.4
---------
Equation:
t = 2.4*s/m
-------------------
How many hours will it take 9 men to build 15 sheds?
t = 2.4*15/9
----
t = 4 hours
