conversations.value: Solve the following math problem: John trains for ultramarathons.  He starts only able to run 8 hours straight but eventually increases that by 75%.  He also increases his speed of 8 mph by 4 mph.  How far can he run now?

conversations.value: He increases the time he can run by 8*.75=6 hours
  So he can now run 8+6=14 hours
  His speed is now 8+4=12 mph
  So he can run 14*12=168 miles
