You have 6 printing presses that made 5000 copies in 6 hours. How many hours would it take 3 printing presses to print 3000 copies
------------
# of hours is directly related to # of copies and inversely related to # of presses
Equation:
# of hrs = k[# of copies/# of presses]
---
Find "k"
6 hrs = k[5000/6 presses]
k = 6*6/5000 = 0.0072
--
So the equation for your problem is the following
# of hrs = 0.0072[# of copies/# of presses]
---
How many hours would it take 3 printing presses to print 3000 copies
# of hrs = 0.0072[3000/3]
# of hrs = 7.2 hrs
