Final answer:
The grade of the mountain path is about 0.061.
Step-by-step explanation:
The grade of a path is the ratio of its vertical drop to its horizontal distance. To find the grade of the mountain path, divide the vertical drop (253.7 feet) by the horizontal distance (4157 feet).
Grade = Vertical drop / Horizontal distance
Grade = 253.7 ft / 4157 ft.
Calculate the grade using a calculator or by dividing 253.7 by 4157:
Grade ≈ 0.061
Therefore, the grade of the mountain path is about 0.061.
