[Question]Hannah's family has ten pigs on their farm. They also have three fewer than twice as many cows as pigs and six more goats than cows. How many animals do they have on their farm?
[Answer]Twice the number of pigs is 10 x 2 = 20. So, Hannah's family has 20 - 3 = 17 cows. They also have 17 + 6 = 23 goats. So, they have a total of 10 + 17 + 23 = 50 animals on their farm. The answer is 50.
Q: In two years, Ophelia will be four times as old as Lennon. If Lennon is currently eight years old, how old is Ophelia?
A: In two years, Lennon will be 2 + 8 = 10 years old. Ophelia will be 4 * 10 = 40 years old in two years. Currently, Ophelia is 40 - 2 = 38 years old. The answer is 38.
Question: Carlos and Diego are racing around the block. Carlos runs around the entire block in 3 minutes. Diego runs around half the block in 2.5 minutes and then is tripped by a dog and can't finish. Assuming he kept up the same speed the entire race, what would've been the average time in seconds for the racers?
Answer: If he finished the race, it would've taken 5 minutes because 2.5 x 2 = 5. Their total time would've been 8 minutes because 3 + 5 = 8. The average would've been 4 minutes because 8 / 2 = 4. The average time in seconds would've been 240 because 4 x 60 = 240. The answer is 240.
[Question]Bridge and Sarah have $3 between them. If Bridget has 50 cents more than Sarah, how many cents does Sarah have?
[Answer]Let X be the amount of money Sarah has, so Bridget has X + 50 cents. We know that Sarah and Bridget combined have $3, or 300 cents, so X + X + 50 = 300. We therefore know that 2X = 250. So Sarah has 250 / 2 = 125 cents. The answer is 125.
Q: John has 2 hives of bees. One of the hives has 1000 bees and produces 500 liters of honey. The second has 20% fewer bees but each bee produces 40% more honey. How much honey does he produce?
A: The second hive has 20 / 100 * 1000 = 200 fewer bees. This translates to 1000 - 200 = 800 bees. Each bee in the first hive produces 1000 / 500 = 2 liters. The second hive has bees each producing 1.4 * 2 = 2.8 liters. The total amount of honey produces by the bees in the second hive is 2.8 * 700 = 1960. The total honey produced is 1960 + 500 = 2460 liters. The answer is 2460.
Question: Joan has 2 hours to get all her music practice done. She spends 30 minutes on the piano, 25 minutes writing music on her computer, and 38 minutes reading about the history of the piano. Her final work is to use a special finger exerciser. How much time does she have left to use this?
Answer:
She has 120 minutes to practice because 2 x 60 = 120. She has already spent 93 minutes on her work because 30 + 25 + 38 = 93. She has 27 minutes to use on finger exercise because 120 - 93 = 27. The answer is 27.
