conversations.value: Tim used to run 3 times a week but decided to add an extra 2 days a week.  She runs 1 hour in the morning and 1 in the evening every day she runs.  How many hours a week does she run now?

conversations.value: He now runs 3+2=5 times a week
  Each day he runs for 1+1=2 hours
  So he runs 2*5=10 hours a week
