Answer:
8 days
Step-by-step explanation:
Direct Variation takes the form 
, and
Inverse Variation takes the form 
Where
and 
are the 2 variables associated, and
is the proportionality constant
From the statement of the problem given, and taking time as 
and length as 
and number of men working as 
We can write:
Using the values given in the problem ( 
, 
, and 
), we can solve for k:
Now, we want to know time given 
and 
and 
So, it will take 8 days.
