Question: Howard is taking his kindergarten class to the museum on a school trip. He splits the class equally into 3 groups and then each of the groups goes through the museum one student at a time. If the class has 18 students in total and each student takes 4 minutes to go through the museum, then how long, in minutes, does it take each group to go through the museum?
Answer: As the groups are equally sized, they must each have 18 students in the class / 3 groups = 6 students in each group. So each group takes 6 students in each group * 4 minutes per each student’s trip = 24 minutes to go through the museum. The answer is 24.

Question: An apple tree can fill 20 baskets. Each basket can be filled with 15 apples. How many apples can you get from 10 trees?

Question: Toby wants to walk an average of 9,000 steps per day over the next week. On Sunday he walked 9,400 steps. On Monday he walked 9,100 steps. On Tuesday he walked 8,300 steps. On Wednesday he walked 9,200 steps. On Thursday he walked 8,900 steps. How many steps does he need to average on Friday and Saturday to meet his goal?
Answer: He needs to walk 63,000 steps in a week because 7 x 9,000 = 63,000. He has 18,100 steps to walk on Friday and Saturday because 63,000 - 9,400 - 9,100 - 8,300 - 9,200 - 8,900 = 18,100. He needs to walk an average of 9,050 on Friday and Saturday because 18,100 / 2 = 9,050. The answer is 9050.

Question: Bert's golden retriever has grown tremendously since it was a puppy. At 7 weeks old, the puppy weighed 6 pounds, but doubled in weight by week 9. It doubled in weight again at 3 months old, and doubled again at 5 months old. Finally, the dog reached its final adult weight by adding another 30 pounds by the time it was one year old. What is the dog's full adult weight, in pounds?
Answer:
At 7 weeks old, the puppy weighed 6 pounds, but doubled in weight by week 9 to reach a weight of 6 * 2 = 12 pounds. It doubled in weight again at 3 months old to reach a weight of 12 * 2 = 24 pounds. It doubled in weight again at 5 months old to reach a weight of 24 * 2 = 48 pounds. And it reached its full adult weight by adding another 30 lbs to reach a final weight of 48 + 30 = 78 pounds. The answer is 78.
