conversations.value: This math problem has got me stumped: Jake decides to go to the beach for a fun day.  It is a 2-hour drive each way.  He then spends 2.5 times at long at the beach as his total driving time.  How much time does the trip take?
  Can you show me the way?

conversations.value: He drives for a total of 2*2=4 hours
  So he spends 4*2.5 =10 hours at the beach
  That means the total trip took 10+4=14 hours
