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?
Let's think: 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.

UF got into the national championship. For them to get into the championship, they scored a total of 720 points during their previous 24 games. In the championship game, however, their opponent was much stronger than any other team they had previously gone against and they scored 2 points less than half as much as they had previously scored in each of the 24 games. Their opponent only lost by 2 points. How many points did their opponent score?
Let's think: They scored an average of 720 / 24 = 30 points in their previous games. Half that many would be 30 / 2 = 15 points. So in the finals, they scored 15 - 2 = 13 points. Their opponent thus scored 13 - 2 = 11 points.. The answer is: 11.

Mrs. Carlton gives out penalty points whenever her students misbehave. They get 5 points for interrupting, 10 points for insulting their classmates, and 25 points for throwing things. If they get 100 points, they have to go to the office. Jerry already interrupted twice and insulted his classmates 4 times. How many times can he throw things before he gets sent to the office?
Let's think: For interrupting, Jerry got 5 points per interruption * 2 interruptions = 10 points. For insulting, he got 10 points per insult * 4 insults = 40 points. To get to the 100 limit points, Jerry has 100 points - 10 points - 40 points = 50 points left. He still has 50 points / 25 points per throw = 2 throws.. The answer is: 2.

Cathy and Chris got summer jobs at the cake shop and were supposed to work 20 hours per week each for 2 months. During that time, Chris got sick for one week and Cathy took her shifts. If there are four weeks in a month, how many hours did Cathy work during the 2 months?
Let's think:
There are 4 weeks in a month so Cathy and Chris were supposed to work for 4 weeks / month x 2 months = 8 weeks each. Since Chris got sick then Chris was only able to work for 8 weeks - 1 week = 7 weeks while Cathy worked for 8 weeks + 1 week = 9 weeks. Therefore, Cathy worked for 9 weeks x 20 hours / week = 180 hours.. The answer is: 180.
