1. The city roads dept. repairs 300,000 potholes, on average, in a year. Critics allege that the dept. is inefficient, given that an average of 60,000 unfilled potholes exist on city roads at any given time (confirmed from official records). The dept. protests the charge, asserting that they fix a pothole, on average, in less than a month. From the numbers provided above, how long does it take the city, on average, to fix a pothole? (Hint: Little's Law: Average Inventory = Average Flow Rate * Average Flow Time) this is my second question
