Q: The pizza delivery person has 12 pizzas to deliver. If two of the stops are for orders of two pizzas and the rest are for single pizzas, how many minutes per stop does the delivery person need to average to deliver all of the pizzas in 40 minutes?
A: If two pizzas will be delivered at two of the stops, the total number of stops will be 12 - 2 = 10 stops. If there are 10 stops in 40 minutes, then the delivery person needs to average 40 / 10 = 4 minutes per stop. The answer is 4.
Question: Jason is planning a parking garage that will have 12 floors. Every 3rd floor has a gate where drivers have to show ID, which takes two minutes. To get from one floor to the next, drivers have to drive 800 feet at 10 feet/second. How long, in seconds, does it take to get to the bottom of the garage from the top?
Answer: First find the total number of gates someone has to pass through: 12 floors / 3 floors / gate = 4 gates. Then find the total time someone spends waiting at the gates: 4 gates * 2 minutes / gate = 8 minutes. Then convert that time to seconds: 8 minutes * 60 seconds / minute = 480 seconds. Then find the time to drive through one floor in seconds: 800 feet / 10 feet / second = 80 seconds. Then multiply the time per floor by the number of floors to find the total driving time: 80 seconds / floor * 12 floors = 960 seconds. Then add the total driving time to the total time waiting at the gates to find the total time to get to the bottom: 960 seconds + 480 seconds = 1440 seconds. The answer is 1440.
[Question]Samuel is going to the cinema with his brother, Kevin. They both have a total budget of $20 for their outing. Samuel buys his $14 ticket, then spends $6 on drinks and food. Kevin buys his ticket, then spends $2 on drinks. They have both used their entire budget. How much did Kevin spend on food?
[Answer]We know Kevin bought a ticket and drinks, and this cost him 14 + 2 = 16 dollars. Since Kevin spent his entire budget, his food must have cost 20 – 16 = 4 dollars. The answer is 4.
Q: A tank with a capacity of 8000 gallons is 3/4 full. Daxton empty's the tank by 40% of the total volume of water in the tank to water his vegetable farm. He then fills the tank with 30% of the volume of water remaining in the tank. Calculate the final volume of water in the tank.
A: The volume of water that is in the tank initially is 3 / 4 * 8000 = 6000 gallons. When Daxton empties 40% of the water, he pumps out 40 / 100 * 6000 = 2400 gallons of water. The total volume of water remaining in the tank is 6000 - 2400 = 3600 gallons. Daxton then fills the tank with 30 / 100 * 3600 = 1080 gallons of water. The final volume of water in the tank is 3600 + 1080 = 4680 gallons. The answer is 4680.
Question: Mary bought 14 apples, 9 oranges, and 6 blueberries. Mary ate 1 of each. How many fruits in total does she have left?
Answer: Mary has 14 - 1 = 13 apples left. Mary has 9 - 1 = 8 oranges left. Mary has 6 - 1 = 5 blueberries left. Mary has 13 + 8 + 5 = 26 fruits left in total. The answer is 26.
Q: A zoo has 16 pandas, paired into mates (in the same zoo). Only 25% of the panda couples get pregnant after mating. If they each have one baby, how many panda babies are born?
A:
First divide the number of pandas by 2 to find the number of couples: 16 pandas / 2 = 8 panda couples. Then multiply that number by 25% to find the number of babies: 8 panda couples * 25% = 2 panda babies. The answer is 2.
