conversations.value: Bill put his french fries in the oven after it finished heating.  The recommended time was 5 minutes for them to be fully cooked.  He put them in for 45 seconds.  How many seconds remained?
  Give me a solution to this problem
conversations.from: assistant
conversations.value: Each minute last 60 seconds, so that means for the fries to be fully cooked Bill needs to cook them for 5*60=300 seconds
  Since Bill had the fries in the oven for 45 seconds so far, that means they need to stay in the oven for another 300-45= 255 seconds.
