Question
The amount of time required to stack boxes varies directly with the number of boxes inversely with the number of people who are stacking them. If 2 people can stack 60 boxes in 10 minutes, how many minutes will be required for 6 people to stack 120 boxes?

2 People: 60boxes/10min . = 6 boxes/min.
6 People: (6/2) * 6 = 18 boxes/min.
T = 120boxes * 1min/18boxes = 6.67 min.
6 People: (6/2) * 6 = 18 boxes/min.
T = 120boxes * 1min/18boxes = 6.67 min.
