Final answer:
The grade for Path A, with a vertical change of 12 meters over a horizontal distance of 34 meters, is 35% when rounded to the nearest percent. For Path B, which has a vertical change of 2 meters over a horizontal distance of 4.27 meters, the grade is 47% after rounding.
Step-by-step explanation:
To calculate the grade of each mountain path to the nearest percent, we will use the formula for grade percentage which is (vertical change / horizontal distance) × 100. The grade percentage provides a numerical measure of the steepness of a path.
For Path A, the vertical change is 12 meters, and the horizontal distance is 34 meters. Therefore, the grade percentage is calculated as follows:
Grade percentage for Path A = (12 / 34) × 100 = 35.2941176%
After rounding to the nearest percent, the grade for Path A is 35%.
For Path B, the vertical change is 2 meters, and the horizontal distance is 4.27 meters. The grade percentage is calculated similarly:
Grade percentage for Path B = (2 / 4.27) × 100 = 46.8367306%
After rounding to the nearest percent, the grade for Path B is 47%.
