conversations.value: I'm stuck on this math problem: An old car can drive 8 miles in one hour. After 5 hours of constant driving, the car needs to get cooled down which takes 1 hour. How many miles can this car drive in 13 hours?
  Can you help?

conversations.value: In 5 hours the car can drive 8 * 5 = 40 miles.
  One cycle of driving and pause takes 5 + 1 = 6 hours.
  In 13 hours this cycle can fit 13 / 6 = 2 full cycles with a remainder of 1 hour
  Two cycles will last for 2 * 6 = 12 hours.
  During two full cycles, the car will drive 40 * 2 = 80 miles.
  So there is 13 - 12 = 1 remaining hour when the car can drive.
  That means during 13 hours the car will be able to drive 80 + 8 = 88 miles.
