Q: A watermelon stand sold 46 watermelons. Seventeen customers bought one melon, three customers bought three melons, and the rest bought two melons. How many customers bought two watermelons?
A: The customers that bought one watermelon bought 1 * 17 = 17 melons. The customers that bought three melons bought 3 * 3 = 9 melons. The stand sold 46 - 17 - 9 = 20 melons to customers who bought 2 melons. Thus, 20 / 2 = 10 customers bought two watermelons. The answer is 10.
Question: Jamie earns $10 an hour by delivering flyers. She delivers flyers 2 days each week. It takes her 3 hours each time she delivers flyers. After delivering flyers for 6 weeks, how much money will she have earned?
Answer: She spends 2 * 3 hours = 6 hours per week delivering flyers. She has spent a total of 6 hours / week * 6 weeks = 36 hours delivering flyers. She has earned a total of 36 hours * $10 / hour = $360. The answer is 360.
[Question]Sadie, Ariana and Sarah are running a relay race. Each part of the race is a different length and covers different terrain. It takes Sadie 2 hours to run through the forest at an average speed of 3 miles per hour. Ariana sprints across the open field on her section at 6 miles per hour for half an hour. If Sarah runs along the beach at four miles per hour and their total time for the race is four and half hours, what is the total distance of the race?
[Answer]Sadie ran for 3 miles / hour * 2 hour = 6 miles. Ariana covered a distance of 6 miles / hour * (1 / 2) hour = 3 miles. Sarah ran for 4.5 hours – 2 hours – 0.5 hours = 2 hours. In this time, Sarah traveled a distance of 4 miles / hour * 2 hours = 8 miles. The total distance for the race was 6 miles + 3 miles + 8 miles = 17 miles. The answer is 17.
Q: William is a jockey. He can ride his horse for 6 hours a day. Over 6 days, he only used the maximum riding time twice. On two days he rode his horse for only 1.5 hours a day and half the maximum time for the next two days. How many hours did William ride his horse during those 6 days?
A: William used two days to the limit, which means 6 * 2 = 12 hours of horse riding. For two days he rode a horse 1.5 a day, which makes up to 1.5 * 2 = 3 hours. For the next two days, he used only half of the maximum time which means 6 * 0.5 = 3 hours a day. That means 2 * 3 = 6 hours during these two days. So in total William rode his horse for 12 + 3 + 6 = 21 hours. The answer is 21.
Question: Aliya and her classmates are sent by their teacher to the field to collect insects for science class study. The Boys collected 200 insects and the girls collected 300 insects. The teacher decided to divide the class equally into four groups that each get an equal number of insects so that each group could study together. What was the number of insects given to each group?
Answer: The total number of insects collected is 200 insects + 300 insects = 500 insects. When the teacher divided the class into four groups, each group got 500 insects / 4 groups = 125 insects / group. The answer is 125.
