conversations.value: Explain how to solve this math problem: Tom goes to a combined undergrad and Ph.D. program.  It takes 3 years to finish the BS and 5 years to finish the Ph.D.  Tom finishes it in 3/4ths the time.  How long does it take for him to finish?

  So he manages to finish in 8*3/4=6 years
