Hitting the Slopes. Many factors determine a ski trails rating, including its width, the presence of obstacles, and the trail’s steepness. Most resorts use the same general classifications: green circles for beginners, blue squares for intermediate skiers, and black diamonds for experienced skiers. In general the following slopes, expressed as percents, are typical for each type of trail. Use this information to solve Exercises 47−48. Round answers to the nearest tenth of a percent. 47. At the Keystone Resort in Colorado, the Schoolmarm Trail starts at an elevation of 11,640 feet and ends at an elevation of 9309 feet. Its run is 15,662 feet. What is the slope of the Schoolmarm Trail and what is the ski trail’s rating?
