Q: Greg drives 30 miles from his workplace to the farmer's market. After buying his groceries at the farmers market, he drives home. To get home, he travels for 30 minutes at 20 miles per hour. How many miles in total does Greg travel?
A: We must first convert minutes to hours, so 30 minutes * (1 hour / 60 minutes) = 0.5 hours. The number of miles Greg travels on his trip home is 0.5 hours * 20 mph = 10 miles. The total miles Greg travels is 10 + 30 = 40 miles. The answer is 40.
Question: Two tribes of soldiers gathered for a battle. The number of women was double the number of cannoneers. There were 63 cannoneers. None of the cannoneers were women. The total number of men is twice the number of women. How many people in total are there?
Answer: There are 63 * 2 = 126 women. The men are 2 * 126 = 252 men. The total number of people are 126 + 252 = 378 people. The answer is 378.
[Question]Each frog needs to eat 30 flies per day to live. Each fish needs to eat 8 frogs per day to live. Each gharial needs to eat 15 fish a day to live. How many flies get eaten every day in this swamp if it has 9 gharials?
[Answer]First find the number of fish the gharials need to eat: 9 gharials * 15 fish / gharial = 135 fish. Then find the number of frogs by multiplying that quantity by the number of frogs per fish: 135 fish * 8 frogs / fish = 1080 frogs. Then multiply the number of frogs by the number of flies each frog eats to find the number of flies: 1080 frogs * 30 flies / frog = 32,400. The answer is 32400.
Q: Pete and Raymond each receive $2.50 from their grandmother. Pete saves his money and only spends 4 nickels. Raymond spends his money at the arcade games but still has 7 dimes left. How much did Pete and Raymond spent altogether, in cents?
A: Pete spends 4 * 5 = 20 cents. Raymond has 7 * 10 = 70 cents left. Raymond spent 250 - 70 = 180 cents. Together, Pete and Raymond spent 20 + 180 = 200 cents. The answer is 200.
Question: Ben took his family fishing yesterday. Ben caught 4 fish, his wife Judy caught 1 fish, his oldest son Billy caught 3, his younger son Jim caught 2, and his youngest child Susie surprised them all by catching 5! Unfortunately, 3 of the fish were too small, so they threw them back. If each fish will give them 2 filets, how many fish filets will Ben and his family have?
Answer: Ben's family caught 4 + 1 + 3 + 2 + 5 = 15 fish. They kept 15 - 3 = 12 fish. They'll get 2 filets per fish, so they will have 12 fish * 2 filets per fish = 24 filets. The answer is 24.
