[Question]Ms. Warren ran at 6 mph for 20 minutes. After the run, she walked at 2 mph for 30 minutes. How many miles did she run and walk in total?
[Answer]20 minutes is 20 / 60 = 1 / 3 of an hour. Ms. Warren ran 6 / 3 = 2 miles. 30 minutes is 30 / 60 = 1 / 2 of an hour. Ms. Warren walked 2 / 2 = 1 mile. Ms Warren ran and walked 2 + 1 = 3 miles in total. The answer is 3.
Q: A couple opened a savings account. The husband gives $335 every week while the wife gives $225 every week. After 6 months of saving (assume 4 weeks in each month), they decided to divide half of the couple's savings into their four children's savings accounts. How much does each child receive?
A: The husband saves $335 x 4 = $1340 a month. The wife saves $225 x4 = $900 a month. Together, they save $1340 + $900 = $2240 in a month. In 6 months, their total savings is $2240 x 6 = $13440. Half of the couple's savings is 13440 / 2 = $6720. Therefore, each child will receive 6720 / 4 = $1680. The answer is 1680.
Question: Marco has $24. Mary has $15. If Marco gives Mary half of what he has, Mary will have more than Marco. But Mary spends $5. How much more money does Mary have than Marco?
Answer: Half of what Marco has is $24 / 2 = $12. If he gives Mary $12, she has $12 + $15 = $27. Now subtract the money Mary spends: $27 - $5 = $22. Now subtract Marco's money from Mary's remaining money, $22 - $12 = $10. The answer is 10.
[Question]A citrus grove has laid out their plans for their sixteen orchards for the growing season. Lemons, their most popular citrus fruit, will take up eight orchards. Oranges are their second most popular fruit and will occupy half as many orchards as the lemons. Limes and grapefruits will split the remaining orchards. How many citrus orchards will be growing grapefruits?
[Answer]Oranges will occupy 8 / 2 = 4 orchards. There will be 16 - 8 - 4 = 4 orchards remaining for limes and grapefruits. Thus, 4 / 2 = 2 orchards will be growing grapefruits. The answer is 2.
Q: A squirrel had stashed 210 acorns to last him the three winter months. It divided the pile into thirds, one for each month, and then took some from each third, leaving 60 acorns for each winter month. The squirrel combined the ones it took to eat in the first cold month of spring before plants were in bloom again. How many acorns does the squirrel have to eat at the beginning of spring?
A: The squirrel split the 210 acorns into thirds, so it had 3 piles of 210 / 3 = 70 acorns. It took 70 - 60 = 10 from each pile. The squirrel will have 3 * 10 = 30 acorns to eat at the beginning of spring. The answer is 30.
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.
