Answer:
No of tractors and Time
Explanation:
Let us suppose that There is only 1 tractor and it take 1 hour to plow 100 acre of farm then it will take 6 hour to completely plow the farm
Now let us suppose that we have 2 tractors Now each tractor will plow 100 acre in 1 hour so they will completely plow the field in 3 hours
In this way if wee keep on increasing the No of Tractors then it will take less time for us to plow the field
In the Form of equation it could be represented as
Let No of tractors represented by trac and time by x
then
trac ∝

trac = constant *

here the constant value is land to be plowed which is 600 acres
so
trac = 600 acres *
