How many machines will be needed to complete a task in 15 days, given that 6 machines can complete the same task in 10 days?
----------
# of machines and # of days are inversely related:
m = k/d
------
Solve for "k":
6 = k/10
k = 60
--------
Equation:
m = 60/d
-----
Ans: m = 60/15 = 4
# of machines needed to complete task in 15 days.
