Q: To make 3 km, Ben walked for 2 hours. Continuing at the same speed, how much time in minutes would it take him to travel 12 km?
A: We have 12 km / 3 km = 4. So, the distance covered in 12 km is 4 times greater than 3 km. The time taken will also be 4 times greater. So, 2 hours x 4 = 8 hours. We convert the time to minutes: 8 hours * 60 minutes / hour = 480 minutes. The answer is 480.
Question: To get free delivery, Alice needs to spend a minimum of $35.00 online at her favorite grocery store. In her cart she has 1.5 pounds of chicken at $6.00 per pound, 1 pack of lettuce for $3.00, cherry tomatoes for $2.50, 4 sweet potatoes at $0.75 each, 2 heads of broccoli for $2.00 each and a pound of Brussel sprouts for $2.50. How much more does she need to spend in order to get free delivery?
Answer: She bought 1.5 pounds of chicken for $6.00 / pound so that's 1.5 * $6 = $9.00. She bought 4 sweet potatoes at $0.75 each so that's 4 * $0.75 = $3.00. She bought 2 heads of broccoli for $2.00 each so that's 2 * $2 = $4.00. The chicken is $9.00, lettuce is $3.00, tomatoes are $2.50, the sweet potatoes are $3.00, broccoli is $4.00 and Brussel sprouts are $2.50 for a total of $9 + $3 + $2.50 + $3 + $4 + $2.5 = $24.00. To get free delivery she needs to spend $35.00, and she already has $24.00 in her cart, so she needs to spend an extra $35 - $24 = $11.00. The answer is 11.
[Question]Barney can perform 45 sit-ups in one minute. Carrie can do twice as many sit-ups per minute as Barney can. And Jerrie can do 5 more sit-ups per minute than Carrie can do. If Barney does sit-ups for 1 minute, and Carrie does sit-ups for two minutes, and Jerrie does sit-ups for three minutes, what would be the combined total number of sit-ups performed?
[Answer]Carrie can do 2 * 45 = 90 sit - ups per minute. Jerrie can do 90 + 5 = 95 sit - ups per minute. In two minutes, Carrie would perform 90 * 2 - 180 sit - ups. And in three minutes, Jerrie would perform 3 * 95 = 285 sit - ups. Thus, in the scenario described, in total, the three would perform 45 + 180 + 285 = 510 sit - ups. The answer is 510.
Q: There was a big sale on cat food at the pet store. 20 people bought cat food that day. The first 8 customers bought 3 cases each. The next four customers bought 2 cases each. The last 8 customers of the day only bought 1 case each. How many cases of cat food were sold?
A: The first 8 customers bought 8 * 3 = 24 cases. The next 4 customers bought 4 * 2 = 8 cases. The last 8 customers bought 8 * 1 = 8. In total 24 + 8 + 8 = 40 cases were sold. The answer is 40.
Question: Debelyn, Christel, and Andrena collect dolls. Debelyn had 20 dolls before she gave Andrena 2 dolls. Christel had 24 dolls before giving Andrena 5 dolls. After all the gifts, Andrena now has 2 more dolls than Christel, how many more dolls does andrena have now than Debelyn?
Answer: Debelyn had 20 - 2 = 18 dolls left after giving out 2 dolls to Christel. Christel had 24 + 2 = 26 dolls after receiving 2 dolls from Debelyn. Christel had 24 - 5 = 19 dolls after giving Andrena 5 dolls. So, Andrena has 19 + 2 = 21 dolls now. Therefore, Andrena has 21 - 18 = 3 more dolls than Debelyn. The answer is 3.
Q: Nancy replaced all of the old vinyl tiles in her bathroom with new hardwood flooring. She replaced flooring in two areas of the bathroom: a 10 foot by 10 foot central area, and a 6 foot by 4 foot hallway. How many square feet of hardwood flooring did Nancy install in her bathroom?
A:
10 feet by 10 feet central area is 10 * 10 = 100 square feet of space. 6 feet by 4 feet hallway is 4 * 6 - 24 square feet of space. Combined, the two areas where she replaced flooring contain 100 + 24 = 124 square feet of space. The answer is 124.
