You can put this solution on YOUR website! If 4 men clean a house in 150 minutes, how long will it take 5 men to complete the same task?
----
# of minutes and # of men are inversely related.
------------
time = k/m
----
Solve for "k" based on "4 men clean a house in 150 minutes":
150 = k/4
k = 600
-----
Equation:
time = 600/m
-----
how long will it take 5 men to complete the same task?
Use the Equation:
time = 600/5 = 120 minutes.
