Question and rationale: The question is: Mike is saving up to buy a house. He puts away 10% of his $150,000 a year salary. He needs to save up 20% of the cost of a $450,000 house for a downpayment. How long will it take?
Step-by-step reasoning process: He saves 150,000 * .1 = $15,000 per year. He needs 450,000 * .2 = $90,000. So he needs to save for 90,000 / 15,000 = 6 years.

Question and rationale: The question is: Micah, Dean, and Jake are all training for a marathon organized by a local NGO to support children in their town who have cancer. Micah runs 2/3 times as fast as Dean. It takes Jake 1/3 times more time to finish the marathon than it takes Mica. If Dean takes 9 hours, what's the total time the three take to complete the marathon?
Step-by-step reasoning process: If Dean takes 9 hours to finish the marathon, it takes Micah 2 / 3 * 9 hours = 6 hours to finish the marathon. It takes Jake 1 / 3 * 6 hours = 2 more hours to finish the marathon than Micah. Jake takes a total of 6 hours + 2 hours = 8 hours to finish the marathon. Micah, Dean, and Jake take a total of 8 hours + 6 hours + 9 hours = 23 hours to finish the marathon.
