Raoul Silva makes dental prosthetics. He has approximately 45 units of WIP inventory at any point in his steady state process, and it takes approximately 235 hours for each unit to flow through the process (he often tells customers that the sky will not fall if they have to wait a bit for his high quality). What is the average time in minutes between each unit produced for his steady state process? 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)
