conversations.value: I need a clearer understanding of how to solve: Every 2 miles a car drives the tires rotate 725 times.  Jeremy drives 400 miles a month.  If each tire can undergo 10,440,000 rotations how many years before the tire needs to be replaced?
conversations.from: assistant
conversations.value: Jeremy drives 400/2=200 segments of 2 miles
  That means each month the car undergoes 200*725=145,000 rotations
  So the tire can last for 10,440,000/145,000=72 months
  That means the tires will last 72/12=6 years
