Q: Saturday at the ice cream shop, there were twice as many people who ordered vanilla ice cream as ordered chocolate ice cream. If 220 people ordered ice cream on Saturday, and 20% of those ordered vanilla ice cream, how many people ordered chocolate ice cream?
A: If 20% of 220 customers ordered vanilla, then there were 0.2 * 220 = 44 customers who ordered vanilla. If there were twice as many people who ordered vanilla as chocolate, then 44 / 2 = 22 customers ordered chocolate. The answer is 22.
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]Vincent has 72 inches of rope that he wants to use for a project, but he needs to cut it into smaller pieces first. He cuts it into 12 equal length pieces, but then he realizes it's too short, so he ties three pieces together. The knots then make each piece 1 inch shorter. How long are his pieces of rope after all this?
[Answer]Each small piece is 6 inches because 72 / 12 = 6. Each piece is then 5 inches long after the knots are tied because 6 - 1 = 5. The three pieces tied together are now 15 inches long because 5 x 3 = 15. The answer is 15.
[Question]A father and a son start approaching each other at the same time from opposite ends of a hallway that is 16m long. If the father is walking three times as fast as the son, at what distance from the father's end of the hallway will they meet?
[Answer]
Since the father is walking 3 times as fast as his son, their speeds are in a ratio of 3:1 respectively. They started at the same time so they will cover distance at the same ratio of 3:1. Each portion of the distance they covered is 16 / (3 + 1) = 4m. The father covered three portions of the distance which is 3 * 4m = 12m from his end. The answer is 12.
