Q: A superhero can use superhuman speed to run 10 miles in 4 minutes. The supervillain has an Evil-Mobile that drives 100 miles per hour. How many miles farther can the superhero run in an hour than the supervillain can drive?
A: There are 60 minutes in an hour, so the superhero will run 60 / 4 = 15 intervals of 10 miles in an hour. Thus, the superhero can run 15 * 10 = 150 miles in an hour. The superhero can run 150 - 100 = 50 miles farther than the supervillain can drive in an hour. The answer is 50.
Question: Before James starts the strength phase training of his cycle he has a powerlifting total of 2200 pounds at a bodyweight of 245 pounds. He manages to gain 15% on his total and 8 pounds of body weight. What is the ratio of his lifting total to bodyweight?
Answer: He added 2200 * .15 = 330 pounds to his total. That means his new title is 2200 + 330 = 2530 pound total. His new body weight is 245 + 8 = 253 pounds. So he has 2530 / 253 = 10 for his ratio. The answer is 10.
[Question]In today's field day challenge, the 4th graders were competing against the 5th graders. Each grade had 2 different classes. The first 4th grade class had 12 girls and 13 boys. The second 4th grade class had 15 girls and 11 boys. The first 5th grade class had 9 girls and 13 boys while the second 5th grade class had 10 girls and 11 boys. In total, how many more boys were competing than girls?
[Answer]When you add up all the girls from all 4 classes, you had 12 + 15 + 9 + 10 = 46 girls. When you add up all the boys from all 4 classes, you had 13 + 11 + 13 + 11 = 48 boys. There are 48 boys and 36 girls so 48 - 46 = 2 more boys. The answer is 2.
Q: Jan buys 5 dozen roses. Each rose cost $6. Since he bought so many he only needs to pay 80%. How much did he pay?
A: He got 5 * 12 = 60 roses. So the cost was 6 * 60 = $360. So he has to pay 360 * .8 = $288. The answer is 288.
Question: A fifth-grade class went on a field trip to the zoo, and their class of 10 students merged with another class with the same amount of students. 5 parents offered to be a chaperone, and 2 of the teachers from both classes will be there too. When the school day was over, the students could choose to go home and 10 of them left. Two of the chaperones were parents in that group, so they left as well. How many individuals were left at the zoo?
Answer: A total of 10 * 2 = 20 students went on the field trip. Some chaperones showed up, letting the group grow to 20 + 5 = 25 individuals. The teachers had to come as well, making the group as big as 25 + 2 = 27 individuals. When the school day ended, 27 - 10 = 17 individuals were left. A couple of chaperones followed suit, leaving 17 - 2 = 15 people at the zoo. The answer is 15.

He needed 2 boxes of candles, because 5 / 2.5 = 2. He needed 24 candles because 2 x 12 = 24. He is 8 because 24 / 3 = 8. The answer is 8.
