Question: John's car gets 30 mpg. He drives 20 miles to work each way 5 days a week. He also drives another 40 miles a week for leisure travel. How many gallons of gas does he use a week?
Answer: Step-by-step reasoning process: He drives 20 * 2 = 40 miles per day for work. So he drives 40 * 5 = 200 miles for work. So he drives a total of 200 + 40 = 240 miles per week. That means he uses 240 / 30 = 8 gallons of gas a week.
So the answer is 8.

Question: Alicia had a wonderful birthday party where she got lots of presents. 10 of the presents were in small boxes. 12 of the presents were in medium boxes. A third of all the presents she is given are in large boxes. How many presents did Alicia get for her birthday?
Answer: Step-by-step reasoning process: Alicia got 10 small boxed presents + 12 medium boxed presents = 22 presents. A third of all the presents Alicia gets are in large boxes, 22 / 2 = 11 is half of the presents we know Alicia got. 11 x 3 = 33 presents Alicia got on her birthday.
So the answer is 33.

Question: TreShaun's full marker has enough ink in it to paint three 4 inch by 4 inch squares. If he colors in two 6 inch by 2 inch rectangles, what percentage of ink is left?
Answer: Step-by-step reasoning process: Each 4 by 4 square equals 16 square inches because 4 x 4 = 16. Three squares equals 48 square inches because 3 x 16 = 48. Each rectangle uses 12 square inches because 2 x 6 = 12. Both rectangles will use 24 square inches because 2 x 12 = 24. He has 1 / 2 of the ink left because 24 / 48 = 1 / 2. He has 50% of the ink left because 1 / 2 x 100 = 50.
So the answer is 50.

Question: In a car racing competition, Skye drove a 6-kilometer track. For the first 3 kilometers, his speed was 150 kilometers per hour. For the next 2 kilometers, his speed was 50 kilometers per hour more. For the remaining 1 kilometer, his speed was twice as fast as his speed on the first 3 kilometers. What is Skye's average speed for the entire race?
Answer:
Step-by-step reasoning process: Since time is obtained by dividing distance and speed, then Skye took 3 km / 150 km per hr. = 1 / 50 of an hour to finish the first 3 kilometers of the race. His speed on the next 2 kilometers was 150 + 50 = 200 kilometers per hour. Hence, it took him 2 km / 200 km per hr. = 1 / 100 of an hour to finish the next 2 kilometers. His speed on the remaining 1 kilometer is 150 x 2 = 300 kilometers per hour. Hence, it took him 1 / 300 of an hour to finish the 1 kilometer. So, the total time it took for Skye to complete the race was 1 / 50 + 1 / 100 + 1 / 300 = 1 / 30 of an hour. Therefore, his average speed for the entire race was 6 km / 1 / 30 hour = 180 kilometers per hour.
So the answer is 180.
