conversations.value: I need help with this problem:
  Bill had to finish a project from work that was to take him 4 days. If he took 6 seven-hour naps in the four days, how long did he spend working on the project?

conversations.value: Since a day has 24 hours, the project was to take 24*4 = 96 hours.
  Bill took 6 seven-hour naps during the four days, a total of 6*7 = 42 hours
  The time he spent working on the project is 96-42 = 54 hours.
