Q: Kristin can run three times faster than Sarith. If Kristin runs 12 times around the adult football field and Sarith runs at the same time around the children's football field that is half the distance as the other field, how many laps did Sarith go around the children's football field?
A: Sarith would run around the adult football field, 12 laps / 3 = 4 laps. So on the children's football field, she managed to run, 4 laps * 2 = 8 laps. The answer is 8.
Question: Nicole has 4 fish tanks. The first two tanks need 8 gallons of water each and the other two need 2 fewer gallons of water each than the first two tanks. If Nicole needs to change the water of the aquarium every week, how many gallons of water will she need in four weeks?
Answer: The first two tanks need 8 x 2 = 16 gallons of water. The other two tanks need 8 - 2 = 6 gallons of water each. So, the two other tanks need 6 x 2 = 12 gallons of water. Nicole needs 16 + 12 = 28 gallons of water every week for her four tanks. Therefore, she needs a total of 28 x 4 = 112 gallons of water in four weeks. The answer is 112.
[Question]A chihuahua, pitbull, and great dane weigh a combined weight of 439 pounds. The pitbull weighs 3 times as much as the chihuahua. The great dane weighs 10 more pounds than triple the pitbull. How much does the great dane weigh?
[Answer]Let x represent the weight of the chihuahua. Pitbull:3x. Great dane:10 + 3(3x) = 10 + 9x. Total:x + 3x + 10 + 9x = 439. 13x + 10 = 439. 13x = 429. x = 33 pounds. Great dane:10 + 9(33) = 307 pounds. The answer is 307.
Q: Tom receives a $12 allowance per month. In the first week, he spends a third of it; in the second week, he spends a quarter of what he has left. How much money does he have left to finish the month?
A: The first week he spends: $12 * 1 / 3 = $4. So he has $12 - $4 = $8 left. In the second week, he spends $8 x 1 / 4 = $2. So Tom has $8 - $2 = $6 left to finish the month. The answer is 6.
Question: A baker bakes 5 loaves of bread an hour in one oven. He has 4 ovens. From Monday to Friday, he bakes for 5 hours, but on Saturday and Sunday, he only bakes for 2 hours. How many loaves of bread does the baker bake in 3 weeks?
Answer: In an hour, the baker bakes 5 x 4 = 20 loaves of bread. From Monday to Friday, he bakes 5 x 20 = 100 loaves of bread per day. From Monday to Friday, he bakes a total of 100 x 5 = 500 loaves of bread. On Saturday and Sunday, he bakes 2 x 20 = 40 loaves of bread per day. On Saturday and Sunday, he bakes a total of 40 x 2 = 80 loaves of bread. In a week, he bakes 500 + 80 = 580 loaves of bread. In 3 weeks, he bakes 580 x 3 = 1740 loaves of bread. The answer is 1740.
