conversations.value: Gary likes to walk around the edge of the local park, which is a rectangle that measures 1.5 miles by 6 miles. If he walks at 3 miles/hour, how many hours does he spend walking?
  Give me a solution to this problem

conversations.value: First find the length of the two long sides of the park: 6 miles * 2 = 12 miles
  Then find the length of the two short sides of the park: 1.5 miles * 2 = 3 miles
  Then add those two lengthes to find the total distance around the park: 12 miles + 3 miles = 15 miles
  Then divide the total length by Gary's speed to find how long he spends walking: 15 miles / 3 miles/hour = 5 hours
