Question and rationale: The question is: Ann can skate 6 miles an hour. Her friend Glenda can skate 8 miles an hour. If they start in the same place and skate in straight lines in opposite directions for 3 hours, how many miles apart do they end up?
Step-by-step reasoning process: First find how far Glenda goes in 3 hours by multiplying her speed by the number of hours she travels: 3 hours * 8 miles / hour = 24 miles. Then do the same thing for Ann: 3 hours * 6 miles / hour = 18 miles. Now add the number of miles both people skated to find the total distance between them: 18 miles + 24 miles = 42 miles.

Question and rationale: The question is: Miss Smith is teaching second period English and is shocked at how small the class seems. There are 6 tables in the classroom with 3 students currently sitting at each table. Sally said 3 girls went to the bathroom, and three times more students went to the canteen. Elliott said that 2 groups of students have recently been added to their class, and each group has 4 students in it. None of these students are in the class right now. Lucas pointed out that a few foreign exchange students have joined the class; 3 from Germany, 3 from France, and 3 from Norway. These students are also missing. How many students are supposed to be in the class?
Step-by-step reasoning process: There are currently 3 * 6 = 18 students sitting in the classroom. There were 3 * 3 = 9 students who went to the canteen. Sally has therefore noticed 3 + 9 = 12 students missing from the class. Elliott said that 2 groups of students have joined the class, so there are another 2 * 4 = 8 students who are not in the classroom. Lucas said that there are 3 + 3 + 3 = 9 foreign exchange students who are not in the classroom. Therefore, there should be 18 + 12 + 8 + 9 = 47 students.

Question and rationale:
The question is: The Franzia wine is three times as old as the Carlo Rosi, while the Carlo Rosi is four times older than the Twin Valley. Calculate the total age of the three brands of wine if the Carlo Rosi is 40 years old.
Step-by-step reasoning process: If the Franzia wine brand is three times as old as the Carlo Rosi, then the Carlo Rosi is 3 * 40 = 120 years old. The total number of years the Carlo Rosi and the Franzia wine brands have been around is 120 + 40 = 160 years. The Carlo Rosi is four times older than the Twin Valley wine brand, meaning the Twin valley wine brand is 40 / 4 = 10 years old. Together, the three bands have a total of 10 + 160 = 170 years of existence.
