conversations.value: Alfie, the albatross, flies 400 kilometers every day.  If the circumference of the earth is 40,000 kilometers, how many days will it take Alfie to fly a distance equal to half of the way around the earth?
  Give me a solution to this problem

conversations.value: Half of 40,000 kilometers is 40,000/2=20,000 kilometers.
  At 400 kilometers per day, it will take Alfie 20,000/400=50 days to fly a distance equal to half the earth's circumference.
