The Magellan Machine Shop produces a certain machined part on its milling machine at the rate of one every 25 seconds. This is a continuous operation that produces parts seven hours per day five days per week. The milling machine is fed parts from an upstream grinding operation. A physical count has revealed that, on the average, there are a total of 1,700 parts ahead of the milling operation waiting to be processed. Use Little's law to determine how long it takes for a part to be milled after it exits the grinding operation.
