conversations.value: On Mondays, he walks 6 miles at 2 miles per hour, for a length of 6/2=3 hours.
  On Wednesdays, he walks 6 miles at 3 miles per hour, for a length of 6/3=2 hours.
  And on Fridays, he runs 6 miles at 6 miles per hour, for a length of 6/6=1 hour.
  The combined total time he spends exercising in a week is 3+2+1=6 hours.
