A factory makes 12 bottles every 2 minutes. The factory makes bottles for 8 hours each work day. What is the fewest number of work days the factory will need to make 28000 bottles
12/2 =6 bottles per minute.
8 x 60 =480 minutes in 1 work-day.
480 x 6 =2,880 bottles made in 1 work-day.
28,000 / 2,880 =9.72, or 9 work-days and about 6 hours, or about ~10 work-days.
