Assume you plan to make boxes together with three classmates and each of you is assigned to exactly one task (A-D). We will not make lids for the boxes this time. Then the stages to make a box should be (in this order) A: Fold horizontially and vertically, unfold, B: Fold four corners, C: Fold sides to center, D: Unfold two sides and reverse fold them to finish. Assume the following amount of work in seconds is required at each station: A: 30 secs, B: 30 secs, C: 45 secs, and D: 59 secs. (Assume you want to make many boxes, i.e., perform the calculations for a continuous process.)
