Q: Mary's sheep can run 12 feet per second, and her sheepdog can run 20 feet per second. A sheep standing 160 feet away from the sheep dog bolts, and the dog runs after it. How many seconds does it take the dog to catch the sheep?
A: 20
Step-by-step reasoning process: First find how much faster the dog is than the sheep: 20 feet / second - 12 feet / second = 8 feet / second. Then divide the distance the dog needs to run by the speed difference: 160 feet / 8 feet / second = 20 seconds.


Q: James spends 10 minutes downloading a game, half as long installing it, and triple that combined amount of time going through the tutorial. How long does it take before he can play the main game?
A: 60
Step-by-step reasoning process: First divide the download time in half to find the install time: 10 minutes / 2 = 5 minutes. Then add that amount of time to the download time: 5 minutes + 10 minutes = 15 minutes. Then triple that amount of time to find the tutorial time: 15 minutes * 3 = 45 minutes. Then add that time to the install and downtime time to find the total time: 45 minutes + 15 minutes = 60 minutes.


Q: Rachel weighs 75 pounds, 6 pounds less than Jimmy and 15 pounds more than Adam. What is the average weight of the three people, in pounds?
A: 72
Step-by-step reasoning process: Jimmy weighs 75 + 6 = 81 pounds. Adam's weight is 75 - 15 = 60 pounds. In total, the three weigh 75 + 81 + 60 = 216 pounds. The average weight of the three is 216 / 3 = 72 pounds.


Q: Reggie and his brother are having a basketball shooting contest. They each get to take 10 shots. Layups are worth 1 point, free throws are worth 2 points, and anything further away is worth 3 points. Reggie makes 3 layups, two free throws, and one long shot. His brother only shoots long shots and makes 4 of them. How many points does Reggie lose by?
A: 2
Step-by-step reasoning process: Reggie makes 3 points off layups because 3 x 1 = 3. Reggie makes 4 points off free - throws because 2 x 2 = 4. Reggie makes 3 points off long shots because 1 x 3 = 3. Reggie scores 10 points because 3 + 4 + 3 = 10. His brother scores 12 points because 4 x 3 = 12. Reggie loses by 2 because 12 - 10 = 2.
