Question: In Zeoland the fine for speeding is $16 for each mile per hour the driver is traveling over the posted speed limit. In Zeoland, Jed was fined $256 for speeding on a road with a posted speed limit of 50 mph. Jed was fined for traveling at what speed in miles per hour?
Answer: First find how much Jed was above the speed limit: $256 fine / $16 for each mile per hour over = 16 miles per hour over. Since the speed limit is 50 mph, this means Jed was driving 50 + 16 = 66 mph. The answer is 66.
[Question]Jean the jaguar has a beautiful fur coat containing a pattern of many rose-shaped spots, as unique as a human fingerprint. Half of her spots are located on her upper torso, with one-third of the spots located on her back and hindquarters, and the remaining spots located on her sides. If Jean has 30 spots on her upper torso, how many spots does she have located on her sides?
[Answer]If 30 is half the number of her spots, then she has 30 * 2 = 60 spots total. If one - third of her spots are located on her back and hindquarters, then she has 60 / 3 = 20 spots located on her back and hindquarters. If the reaming spots are located on her sides, then 60 - 30 - 20 = 10 spots are located on her sides. The answer is 10.

A: A team of 5 firefighters with hoses can deliver 5 * 20 = 100 gallons of water per minute. To deliver 4000 gallons, this team will take 4000 / 100 = 40 minutes to extinguish the fire. The answer is 40.
