Q: Jason is making pasta. He fills the pot with 41 degree water. Each minute the temperature of the water increases by 3 degrees. Once the water reaches 212 degrees and is boiling, Jason needs to cook his pasta for 12 minutes. Then it will take him 1/3 that long to mix the pasta with the sauce and make a salad. How many minutes does it take Jason to cook dinner?
A: First find how many degrees the temperature of the water needs to increase: 212 degrees - 41 degrees = 171 degrees. Then divide that amount by the number of degrees the water temperature increases each minute to find how long it takes the water to boil: 171 degrees / 3 degrees / minute = 57 minutes. Now figure out how long it takes to mix the pasta and make salad by dividing the pasta cook time by 3: 12 minutes / 3 = 4 minutes. Now add the boiling time, cook time, and mixing time to find the total time it takes to make dinner: 57 minutes + 4 minutes + 12 minutes = 73 minutes. The answer is 73.
Question: Leila and her friends want to rent a car for their one-day trip that is 150 kilometers long each way. The first option for a car rental costs $50 a day, excluding gasoline. The second option costs $90 a day including gasoline. A liter of gasoline can cover 15 kilometers and costs $0.90 per liter. Their car rental will need to carry them to and from their destination. How much will they save if they will choose the first option rather than the second one?
Answer: Leila and her friends will travel a total distance of 150 x 2 = 300 kilometers back - and - forth. They will need 300 / 15 = 20 liters of gasoline for this trip. So, they will pay $0.90 x 20 = $18 for the gasoline. Thus, the first option will costs them $50 + $18 = $68. Therefore, they can save $90 - $68 = $22 if they choose the first option. The answer is 22.
[Question]Dan can get to the center of a lollipop in 58 licks. Micheal does it in 63 licks. Sam & David each take 70 licks to get to the center of a lollipop while Lance only needs 39 licks. What is the average amount of licks it takes to get to the center of a lollipop?
[Answer]Dan takes 58 licks, Michael takes 63, Sam takes 70, David takes 70 and Lance takes 39 for a total of 58 + 63 + 70 + 70 + 39 = 300 licks. There are 5 people and the total amount of licks is 300 so the average is 300 / 5 = 60 licks to get to the center of a lollipop. The answer is 60.
[Question]Nancy and Rose are making bracelets, and there are eight beads in each bracelet. Nancy has 40 metal beads and 20 more pearl beads. Rose has 20 crystal beads and twice as many stone beads as crystal beads. How many bracelets can Nancy and Rose make?
[Answer]
Nancy has 40 + 20 = 60 pearl beads. So, Nancy has a total of 40 + 60 = 100 beads. Rose has 2 x 20 = 40 stone beads. So, Rose has 20 + 40 = 60 beads. Thus, Nancy and Rose have 100 + 60 = 160 beads altogether. Therefore, they can make 160 / 8 = 20 bracelets. The answer is 20.
