Reasoning and answer: So far Alex and Max are running the race for 200 + 300 + 170 + 440 = 1,110 feet. If the road they're racing each other on is 5000 feet long, 5000 - 1,110 feet = 3,890 feet left for Max to catch up to Alex.
The answer: 3890

Question: Alex and Max are running a race against each other. At the beginning of the race they are even with each other for 200 feet. Then Alex gets ahead of Max by 300 feet. Then Max gets ahead of Alex by 170 feet. Alex gets a burst of speed and gets ahead of Max by 440 feet. If the road they're running on is 5000 feet long, how many feet are there left for Max to catch up to Alex?


Bella needs a total of 8 beads x 6 friends = 48 beads. She needs 48 beads – 36 beads = 12 more beads.
The answer: 12
Reverse engineering the question: Bella is making bracelets for her 6 friends. She needs 8 beads per bracelet. She has 36 beads. How many more beads does she need to make all six bracelets?


Reasoning and answer: Counting the cats he had, the kittens he found, and the injured cat, Jeff had a total of 20 + 2 + 1 = 23 cats. 3 people took a total of 3 * 2 = 6 cats. After Wednesday, Jeff was left with 23 - 6 = 17 cats.
The answer: 17

First, add three to Joey's vote total: 8 votes + 3 votes = 11 votes. Then double that number to find the number of votes Barry got: 11 votes * 2 = 22 votes. Then triple that number to find Marcy's vote total: 22 votes * 3 = 66 votes.
The answer: 66
Reverse engineering the question: Marcy's grade is electing their class president. Marcy got three times as many votes as Barry, who got twice as many as 3 more than the number of votes Joey got. If Joey got 8 votes, how many votes did Marcy get?


Reasoning and answer: Since time is obtained by dividing distance and speed, then Skye took 3 km / 150 km per hr. = 1 / 50 of an hour to finish the first 3 kilometers of the race. His speed on the next 2 kilometers was 150 + 50 = 200 kilometers per hour. Hence, it took him 2 km / 200 km per hr. = 1 / 100 of an hour to finish the next 2 kilometers. His speed on the remaining 1 kilometer is 150 x 2 = 300 kilometers per hour. Hence, it took him 1 / 300 of an hour to finish the 1 kilometer. So, the total time it took for Skye to complete the race was 1 / 50 + 1 / 100 + 1 / 300 = 1 / 30 of an hour. Therefore, his average speed for the entire race was 6 km / 1 / 30 hour = 180 kilometers per hour.
The answer: 180

Question: In a car racing competition, Skye drove a 6-kilometer track. For the first 3 kilometers, his speed was 150 kilometers per hour. For the next 2 kilometers, his speed was 50 kilometers per hour more. For the remaining 1 kilometer, his speed was twice as fast as his speed on the first 3 kilometers. What is Skye's average speed for the entire race?


Reasoning and answer: If Ariella has $200 more in her son's saving account than Daniella has, then she has $400 + $200 = $600. If she earns an interest of 10% in the first year, her savings account increases by 10 / 100 * $600 = $60. In the second year, she earns the same amount of interest, which $60 + $60 = $120. The total amount of money in Ariella's account after two years is $600 + $120 = $720.
The answer: 720
