[Question]Jesse and Mia are competing in a week long race. They have one week to run 30 miles. On the first three days Jesse averages (2/3) of a mile. On day four she runs 10 miles. Mia averages 3 miles a day over the first 4 days. What is the average of their average that they have to run over the final three days?
[Answer]Jesse runs 2 miles in the first three days because 3 x (2 / 3) = 2. Jesse has 18 miles left to run because 30 - 10 - 2 = 18. Jesse has to run an average of 6 miles a day because 18 / 3 = 6. Mia runs 12 miles over the first four days because 4 x 3 = 12. She has 18 miles left to run because 30 - 12 = 18. She has to run six miles a day because 18 / 3 = 6. The total they both have to run is 12 miles a day. The average they have to run per day on average is 6 miles because 12 / 2 = 6. The answer is 6.
Q: John builds a box. The box is 26 inches by 26 inches by 14 inches. The walls are 1 inch thick on each side. How much is the internal volume in cubic feet?
A: The walls take away 2 * 1 = 2 inches from each dimension. So the longer sides are 26 - 2 = 24 inches. That is 24 / 12 = 2 feet. The smaller dimension is 14 - 2 = 12 inches. That is 12 / 12 = 1 foot. So the internal volume is 2 * 2 * 1 = 4 cubic feet. The answer is 4.
Question: Tina decides to fill a jar with coins. In the first hour she puts in 20 coins. During the next two hours she puts in 30 coins each time. During the fourth hour she puts in 40 coins. During the fifth hour her mother asks to borrow some money so she takes 20 coins out. How many coins are left after the fifth hour?
Answer: There are 20 coins during the first hour. 30 coins are added during the second and third hours and 40 coins are added during the fourth hour. By the fourth hour there are 20 + 30 + 30 + 40 = 120 coins. The number of coins after giving 20 to her mother is 120 - 20 = 100. The answer is 100.
[Question]Carson is a night security guard. He's supposed to patrol the outside of a warehouse that's 600 feet long and 400 feet wide. If Carson is supposed to circle the warehouse 10 times, but gets tired and skips 2 times, how far does he walk in one night?
[Answer]First find the total distance Carson walks along the warehouse's long sides: 600 feet / side * 2 sides = 1200 feet. Then find the total distance Carson walks along the warehouse's short sides: 400 feet / side * 2 sides = 800 feet. Add those two amounts to find the total distance walk in one circle: 1200 feet + 800 feet = 2000 feet. Then find the number of circles Carson actually walks: 10 circles - 2 circles = 8 circles. Then multiply the distance of one circle by the number of circles Carson makes: 2000 feet / circle * 8 circles = 16000 feet. The answer is 16000.
Q: There is a very large room that has 4 tables, 1 sofa and 2 chairs that have 4 legs each. There are also 3 tables with 3 legs each, 1 table with 1 leg, and 1 rocking chair with 2 legs. How many legs are there in the room?
A: There are 4 tables, 1 sofa and 2 chairs that have 4 legs each so 4 + 1 + 2 = 7 pieces of furniture. These 7 pieces have 4 legs each so they have 7 * 4 = 28 legs. There are 3 tables with 3 legs each so they have 3 * 3 = 9 legs. We have 28 legs and 9 legs as well a 1 leg on a table and 2 on a rocking chair for a total of 28 + 9 + 1 + 2 = 40 legs. The answer is 40.
