conversations.value: Provide a step by step solution for the following math problem: Tony loved to solve difficult pen and paper puzzles.  He did a warm-up puzzle that only took 10 minutes and after that he did 2 puzzles that each took 3 times as long.  How long did he spend solving puzzles?

conversations.value: Each of the long puzzles took 3*10=30 minutes to solve
  So he spent 30*2=60 minutes solving them
  That means he spent 60+10=70 minutes solving puzzles
