He did 5 races in the lake because 10 / 2 = 5. He did 5 races in the ocean because 10 / 2 = 5. He raced 15 miles in the lake because 5 x 3 = 15. His lake races took 6 hours because 15 / 2.5 = 6. He raced 15 miles in the ocean because 5 x 3 = 15. His ocean races took 5 hours because 15 / 3 = 5. He spent 11 hours racing because 5 + 6 = 11.
The answer: 11
Reverse engineering the question: Tyson can swim at a speed of 3 miles per hour in a lake and 2.5 mph in an ocean. This season, half his races happened in lakes and half his races happened in the ocean. He had ten total races, each of which was 3 miles long. How much time did he spend in his races?


Reasoning and answer: The two sets of plates amount to $20 x 2 = $40. So the table and the two sets of plates amount to $50 + $40 = $90 in all. Since Jude received a $4 change, then he paid a total of $130 - $4 = $126 for the chairs, tables, and plates. Thus, the three chairs cost $126 - $90 = $36. Therefore, each chair cost $36 / 3 = $12.
The answer: 12

Ellen takes 4 * 3 = 12 hours in total to rise all balls of dough. It will take 4 * 2 = 8 more hours to bake each one. It will take her 12 + 8 = 20 hours to make all of the bread.
The answer: 20
Reverse engineering the question: Ellen is baking bread. It takes 3 hours to rise 1 ball of dough, and then another 2 hours to bake it. If she makes 4 balls of dough one after another and then bakes them one after another when they're done rising, how many hours will it take?


Reasoning and answer: The sandbox is 3' long, 3' wide so the sq footage of the sandbox is 3 * 3 = 9 sq ft. He needs 9 sq ft of sand to fill the sandbox and he can buy it in 3 sq ft bags so he needs 9 / 3 = 3 bags of sand. The sand costs $4.00 a bag and he needs 3 bags so it will cost him 4 * 3 = $12.00 in sand.
The answer: 12
