Step-by-step reasoning process: The number of photos in the first batch of pages is 12 * 2 = 24 photos. The number of photos in the second batch is 9 * 3 = 27 photos. The total number of photos used in the newspaper is 24 + 27 = 51 photos.
The question and answer:
Question and answer: In a newspaper, each one of 12 pages holds 2 photos and each of another 9 pages hold 3 photos. How many photos are used in the newspaper?
The answer is 51

Step-by-step reasoning process: If Dean takes 9 hours to finish the marathon, it takes Micah 2 / 3 * 9 hours = 6 hours to finish the marathon. It takes Jake 1 / 3 * 6 hours = 2 more hours to finish the marathon than Micah. Jake takes a total of 6 hours + 2 hours = 8 hours to finish the marathon. Micah, Dean, and Jake take a total of 8 hours + 6 hours + 9 hours = 23 hours to finish the marathon.
The question and answer:
Question and answer: Micah, Dean, and Jake are all training for a marathon organized by a local NGO to support children in their town who have cancer. Micah runs 2/3 times as fast as Dean. It takes Jake 1/3 times more time to finish the marathon than it takes Mica. If Dean takes 9 hours, what's the total time the three take to complete the marathon?
The answer is 23

Step-by-step reasoning process: First find the total number of people by adding the number of passengers and flight crew: 30 people + 5 people = 35 people. Then find the total number of bags by doubling the total number of people: 35 people * 2 bags / person = 70 bags. Then find the fuel increase caused by the people by multiplying their number by the fuel increase per person: 35 people * 3 gallons / mile / person = 105 gallons / mile. Then multiply the number of bags by the fuel increase per bag to find the total fuel increase they cause: 70 bags * 2 gallons / mile / bag = 140 gallons / mile. Now add the fuel increases to the base fuel consumption to find the total fuel needed per mile: 140 gallons / mile + 105 gallons / mile + 20 gallons / mile = 265 gallons / mile. Now multiply the fuel consumption per mile by the number of miles flown to find the total amount of fuel needed: 265 gallons / mile * 400 miles = 106,000 gallons of fuel.
The question and answer:
Question and answer:
Carol is an aviation engineer deciding how much fuel to put in a jet. The empty plane needs 20 gallons of fuel per mile. Each person on the plane increases this amount by 3 gallons per mile, and each bag increases it by 2 gallons per mile. If there are 30 passengers and 5 flight crew, and each person brought two bags, how many gallons of fuel does the plane need for a 400-mile trip?
The answer is 106000
