Q: Melinda is taking a 1200-mile trip with her family to visit their cousins. How much time will they save if they drive 60 miles an hour instead of 50 miles an hour?
A: Going 60 mph, the trip would take 1200 - mile trip / 60 miles an hour = 20 hours. Going 50 mph, the trip would take 1200 - mile trip / 50 miles an hour = 24 hours. Melinda’s family would save 24 – 20 = 4 hours. The answer is 4.
Question: Marcus scored 5 3-point goals and 10 2-point goals. If his team scored 70 points overall, what percentage of the team's total points did Marcus score?
Answer: First find the total number of points Marcus scored through 3 - point goals: 5 goals * 3 points / goal = 15 points. Then find the total number of points he scored through 2 - point goals: 10 goals * 2 points / goal = 20 points. Then add those amounts to find the total number of points Marcus scored: 15 points + 20 points = 35 points. Finally, divide that number by the team's total number of points and multiply by 100% to find the percentage of points Marcus scored: 35 points / 70 points * 100% = 50%. The answer is 50.
[Question]Darnell has 1000 square feet of fabric that he's using to make mini flags. He makes square flags that are 4 feet by 4 feet, wide rectangular flags that are 5 feet by 3 feet, and tall rectangular flags that are 3 feet by 5 feet. He has already made 16 square flags, 20 wide flags, and 10 tall flags. How many square feet of fabric does he have left?
[Answer]The square flags use 16 square feet of fabric per flag because four times four equals 16. The wide flags each use 15 feet of fabric per flag because five times three equals 15. The tall flags each use 15 feet of fabric per flag because five times three equals 15. He has used 256 square feet for the square flags because 16 times 16 equals 256. He has used 300 square feet for the wide flags because 20 times 15 equals 300. He has used 150 square feet for the tall flags because ten times 15 equals 150. He has used 706 square feet because 256 plus 300 plus 150 equals 706. He has 294 square feet left because 1,000 minus 706 equals 294. The answer is 294.
Q: At the end of the first quarter, the winning team had double the points of the losing team. At the end of the second quarter, the winning team had 10 more points than it started with. At the end of the third quarter, the winning team had 20 more points than the number it had in the second quarter. If the total points the winning team scored in the game was 80, and the losing team had 10 points in the first quarter, calculate the total number of points the team scored in the fourth quarter.
A: At the end of the first quarter, the winning team had double the points of the losing team, meaning the winning team had already scored 10 * 2 = 20 points. At the end of the second quarter, the winning team had 10 more points than it started with, a total of 20 + 10 = 30 points. At the end of the third quarter, the winning team had 20 more points than the number it had in the second quarter, a total of 20 + 30 = 50 points. If the total points the winning team scored in the game was 80, they scored 80 - 50 = 30 points in the fourth quarter. The answer is 30.
