Q: Buffy has a sailboat with a planing hull that she sails in the Gulf of Mexico. Under optimal wind conditions, the use of two sails brings the ship to the speed of 50 knots, whereas under the same conditions, the use of one sail brings her ship to the speed of 25 knots. A knot is a nautical term for speed equal to 1 nautical mile per hour, and one nautical mile equals 1.15 land miles. If she travels in her sailboat under optimal wind conditions for 4 hours with one sail and then for another 4 hours with two sails, what is the total distance, in land miles, that she will travel?
A: Under optimal wind conditions, if her ship sails 4 hours with 1 sail, she will travel 4 * 25 = 100 nautical miles. Under optimal wind conditions, if her ship sails 4 hours with 2 sails, she will travel 4 * 50 = 200 nautical miles. In total, she will travel 100 + 200 = 300 nautical miles. If 1 nautical mile is equivalent to 1.15 land miles, then Buffy will travel 300 * 1.15 = 345 land miles. The answer is 345.
Question: Claudia has 122 ounces of water and is filling up cups. She has 8-ounce glasses, 5-ounce glasses, and 4-ounce glasses. If she fills six 5 ounce glasses and four 8 ounce glasses, how many 4 ounce glasses can she fill with the remaining water?
Answer: She has used 32 ounces on 8 - ounce glasses because 4 x 8 = 32. She has used 30 ounces on the 5 - ounce glasses because 6 x 5 = 30. She has used 62 ounces in total because 32 + 30 = 62. She has 60 ounces left because 122 - 62 = 60. She can fill fifteen four - ounce glasses because 60 / 4 = 15. The answer is 15.
[Question]Doris works at the Widget Factory in the packing department. She puts 3 widgets in each carton, which are 4 inches wide, 4 inches long, and 5 inches tall. She then packs those cartons into a shipping box before sending it to the loading bay. The shipping boxes are 20 inches wide, 20 inches long, and 20 inches high. How many widgets get shipped in each shipping box?
[Answer]Each carton has an area of 4 * 4 * 5 = 80 square inches. Each shipping box has an area of 20 * 20 * 20 = 8000 square inches. The total number of cartons that will fit into each box is 8000 / 80 = 100. Since there are 3 widgets in each carton, the total number of cartons in each box will be 3 * 100 = 300. The answer is 300.
Q: A watermelon weighs 23 pounds. If Farmer Kent sells his special watermelons for $2 a pound, how much money would he make for selling 18 watermelons of the same weight?

Question: Clare's mother gave her $47 to go to the store. Clare bought 4 loaves of bread and 2 cartons of milk. Each loaf of bread cost $2 and each carton of milk cost $2. How much money does Clare have left?
Answer: The cost of the loaves of bread is 4 × $2 = $8. The cost of the milk is 2 × $2 = $4. The total cost of the groceries is $8 + $4 = $12. Clare has $47 − $12 = $35 left. The answer is 35.

Week 1:600 / 2 = 300. 600 - 300 = 300 pages remain. Week 2:300(.30) = 90 pages. 300 - 90 = 210 pages remain. Week 3:210 pages. The answer is 210.
