4 cows can plough 7 hectares of field in 3 days. how many hectare of field can be ploughed by six cows in 8 day
------
hectares are directly related to # of cows and number of days
----------------------
h = k*c*d
----
Solve for "k" using "4 cows can plough 7 hectares in 3 days"
----
7 = k*4*3
k = 7/12
------
Equation:
h = (7/12)*c*d
----
How many hectares of field can be ploughed by six cows in 8 days?
h = (7/12)(6*8)
---
# of hectares = 7*4 = 28
