Yu Shu Lien's company makes dragon and tiger figurines. On average she holds 300 units of WIP inventory, and there are 9 minutes between each one made. How many production hours (don't worry about the number of working hours each day for this question) does each figurine spend in the production system? Go to at least three decimal places for intermediate steps (so 12.1786 would be rounded as 12.179) and one decimal place for your final answer (so 12.1793 would be rounded as 12.2).
