Reasoning and answer: In 3 hours, Liza reads 20 x 3 = 60 pages. In 3 hours, Suzie reads 15 x 3 = 45 pages. Liza reads 60 - 45 = 15 pages more than Suzie.
The answer: 15

Question: Liza reads 20 pages in an hour, and Suzie reads 15 pages in an hour. How many more pages does Liza read than Suzie in 3 hours?
If "x" is the number of European swallows, then, for every one European swallow, there would be 2x American swallows. Thus, the total number of swallows would be 2x + x = 90 swallows. Thus, the number of European swallows x = 30. And the number of American swallows is 90 - 30 = 60. A European swallow can carry twice what an American swallow can carry, or 2 * 5 = 10 pounds. 30 European swallows can carry a maximum of 30 * 10 = 300 pounds. 60 American swallows can carry a maximum of 60 * 5 = 300 pounds. Thus, a flock of 90 birds, with 30 European and 60 American swallows, can carry 300 + 300 = 600 pounds.
The answer: 600
Reverse engineering the question: The American swallow can lift into the air and carry a maximum of 5 pounds of weight, while the European swallow can lift and carry twice the weight as the American swallow. If there was a flock of 90 swallows, containing twice as many American as European swallows, what is the maximum combined weight the flock can carry?
Reasoning and answer: Let L be the length and W be the width of the rectangle. Hence L = 4 * W. We now use the area to write 80 = L * W. Substitute L by 4 W in the equation above 80 = 4 * W W = 4 W^2. Solve for W and find L. 4 W^2 = 100. W^2 = 25, W = 5 and. L = 4 * 5 = 20 m.
The answer: 20

Question: The length of a rectangle is four times its width. If the area is 100 m2. what is the length of the rectangle?
Let x = the percent needed on her third math test. (95 + 80 + x) / 3 = 90. (95 + 80 + x) = 270. x = 270 - 95 - 80. x = 95.
The answer: 95
Reverse engineering the question: Kat gets a 95% on her first math test and an 80% on her second math test. If she wants an average grade of at least 90% in her math class, what does she need to get on her third final math test?
Reasoning and answer: The multiple - choice questions will take her a total of 30 * 15 = 450 minutes. The fill - in - the - blank questions will take her a total of 25 * 30 = 750 minutes. The test will take her a total of 450 + 750 = 1200 minutes to study for. Therefore, Martiza will need to study a total of 1200 / 60 minutes = 20 hours.
The answer: 20

Question: Martiza is studying for the citizenship test. There are 60 questions on the test. 30 are multiple-choice and 30 are fill-in-the-blank. It takes her 15 minutes to learn each multiple-choice question and 25 minutes each to learn the fill-in-the-blank questions. How many hours will she need to study before she is ready for the test?
Reasoning and answer: Tony got twice $1750 which is 2 * $1750 = $3500. The total amount shared was $1750 + $3500 = $5250.
The answer: 5250
