conversations.value: Can you give me some step-by-step instructions for this math problem: The last time Bob cut his hair he cut it to 6 inches.  His hair is now 36 inches long.  If hair grows at a rate of .5 inches per month how many years did it take him to grow out his hair?
conversations.from: assistant
conversations.value: His hair grew 36 inches - 6 inches = 30 inches
  Hair grows at a rate of 12 months/year * 0.5 inches/month =6 inches/year
  It took him 30 inches / 6 inches/year = 5 years to grow his hair out.
