You can put this solution on YOUR website! One man can dig a canal in 60 days. How many days will 5 men take if they work at the same rate?
-----
# of days and # of men are inversely related::
d = k/m
-----
Solve for "k" using "one man can dig a canal in 60 days"::
60 = k/1
k = 60
--------
Equation:
d = 60/m
-----
How many days will 5 men take if they work at the same rate?
d = 60/5 = 12 days
