conversations.value: To make a living, Carl needs to drive a car for 2 hours every day. After he got promoted he needs to drive for 6 more hours every week. How many hours will Carl drive in two weeks?
conversations.from: assistant
conversations.value: Every week Carl needs to drive additional 6 hours, so in two weeks that would make 2 * 6 = 12 additional hours.
  Two weeks of driving 2 hours every day, means 14 * 2 = 28 hours of driving.
  So during two weeks, Carl will drive 28 + 12 = 40 hours.
