conversations.value: Break down this math problem: Bob is tilling a plot of his garden. The plot is 110 feet wide by 120 feet long. His tiller digs a swath two feet wide, and he can till 1 foot of ground in about 2 seconds. How long will it take him to till this plot of land, in minutes?

conversations.value: If Bob goes along the side that's 120 feet long, he will till 110 / 2 = 55 rows.
  Each of these rows are 120 feet long, so he will push the tiller a total of 120 * 55 = 6,600 feet.
  He tills 1 linear foot of ground every 2 seconds, so it will take him 2 * 6,600 = 13,200 seconds to till this plot
  13,200 seconds is 13,2000 / 60 = 220 minutes
