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? Give the rationale and then the answer.
Let's think step by step. 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.. The answer is: 220.

Alan likes to support music creators, so instead of downloading songs from the internet, he visits a record store once in a while. He decided now to buy 2 CDs by "The Dark", 1 CD by the creator "AVN", and 5 CDs that are mixes of songs from the 90s. The price of the "AVN" CD is $12 and it is half the price of one CD by "The Dark". The 5 CDs of 90s music cost is 40% of all the cost of all other CDs Alan is going to buy. How much will Alan have to pay for all the products? Give the rationale and then the answer.
Let's think step by step. If one "AVN" is half the price of one "The Dark" CD, that means one CD of "The Dark" costs 12 * 2 = $24. So for two "The Dark" CDs, Alan needs to pay 24 * 2 = $48. So all CDs cost by now 12 + 48 = $60. The 90s music CDs cost 40 / 100 * 60 = $24. That means for all CDs Alan needs to pay 60 + 24 = $84.. The answer is: 84.

The tornado picked up the Smith's car and transported it 200 feet in the air before dropping it into the neighbors' pool. Also in the pool was a lawn chair that had been blown twice as far as the car had been transported. And the pool also contained a birdhouse that had flown through the air three times farther than the lawn chair had been blown. How far, in feet, far had the birdhouse flown? Give the rationale and then the answer.
Let's think step by step. The lawn chair was blown twice as far as the car, or 2 * 200 = 400 feet. The birdhouse had flown 3 times farther than the lawn chair had been blown, or 3 * 400 = 1200 feet.. The answer is: 1200.
