A recipe for a large batch of cookies requires 4 cups of flour, 2 cups of sugar, and 1 cup of butter. If you want to make a batch that is three times larger, how many cups of each ingredient will you need, and what will be the new ratio of flour to sugar to butter?

A mountain climber ascends 3,000 feet in the first hour but then descends 800 feet in the next hour to rest. If the climber continues this pattern, ascending 3,000 feet in the first hour and descending 800 feet in the next, how many hours will it take for the climber to reach the peak of a 20,000-foot mountain?
Each two-hour cycle results in a net gain of 2,200 feet (3,000 feet up - 800 feet down). To reach 20,000 feet, the climber will need to complete 9 full cycles (18 hours) to gain 19,800 feet. In the 10th cycle, the climber will ascend 3,000 feet in the first hour, reaching the peak at 20,000 feet, so it will take an additional 1 hour. Therefore, the total time is 18 hours (9 cycles) + 1 hour, which equals 19 hours.
