-----
Note: 4 men take 60 hrs
---
# of men and time to do the job are indirectly related.
--------------------------
hrs = k/m
---
Solve for "k" using "4 men take 60 hrs"
60 = k/4
k = 240
-----
Equation:
days = 240/men
------------------------
Solve "how many days would it take 6 men to mow the same land if they worked 8 hours per day?"
---
hrs = 240/6
hrs = 40 hours
# of days = 40/8 = 5 days
