Q: Kim drives 30 miles to her friend's house. On the way back she has to take a detour that is 20% longer. She spends 30 minutes at her friend's house. She drives at a speed of 44 mph. How long did she spend away from home?
A: The trip back was 30 * .2 = 6 miles longer than the trip there. So it was 30 + 6 = 36 miles. So the total drive was 30 + 36 = 66 miles. That means she drove for 66 / 44 = 1.5 hours. She stayed with her friend 30 / 60 = .5 hours. So the total time was 1.5 + .5 = 2 hours. The answer is 2.
Question: Camila has only gone hiking 7 times in her life. Amanda has gone on 8 times as many hikes as Camila, and Steven has gone on 15 more hikes than Amanda. If Camila wants to say that she has hiked as many times as Steven and plans to go on 4 hikes a week, how many weeks would it take Camila to achieve her goal?
Answer: Amanda has gone on 7 hikes x 8 = 56 hikes. Steven has gone on 56 hikes + 15 hikes = 71 hikes. Camila needs to go on another 71 hikes - 7 hikes = 64 hikes. Camila will achieve her goal in 64 hikes / 4 hikes / week = 16 weeks. The answer is 16.
[Question]A road has four lanes, and in each lane, the number of cars is twice as many as the number of trucks in all the lanes. If there are 60 trucks in each lane, calculate the total number of vehicles in all the lanes?
[Answer]If the road has four lanes and 60 trucks in each lane, the total number of trucks in all the lanes is 60 * 4 = 240. Since in each lane the number of cars is twice as many as the number of trucks in all the lanes, there are 2 * 240 = 480 cars in each lane. The total number of cars in all the lanes is 480 * 4 = 1920. In all the lanes, the total number of vehicles is 240 trucks + 1920 cars = 2160. The answer is 2160.
Q: Frank spent 1/5 of his money to buy groceries. He then spent 1/4 of the remaining money to buy a magazine. If he had $360 left in his wallet, how much money did he have at first?
A: Let X be the money Frank had originally. Frank spent 1 / 5 * X on groceries. Frank spent 1 / 4 * (X - 1 / 5 * X) on a magazine. Frank has X - 1 / 5 * X - 1 / 4 * (X - 1 / 5 * X) = $360 left in his wallet. Multiplying through the parentheses, we get X - 1 / 5 * X - 1 / 4 * X + 1 / 20 * X = $360. Combining like terms, we get 12 / 20 * X = $360. Dividing both sides by 12 / 20, we get X = $600. The answer is 600.
Question: Jared likes to draw monsters. He drew a monster family portrait. The mom had 1 eye and the dad had 3. They had 3 kids, each with 4 eyes. How many eyes did the whole family have?
Answer: The mom and dad monsters had 1 + 3 = 4 eyes. The 3 kids had 4 eyes each, so 3 x 4 = 12 eyes. Altogether, the monster family had 4 parent eyes + 12 child eyes = 16 eyes. The answer is 16.
Q: Tire repair for each tire costs $7, plus another 50 cents for sales tax. If Juan needs all 4 tires repaired, how much is the final cost?
