What is the gradient of a volcanic cone that has a height of 5340 feet and a base

245 feet per mile

Explanation:

The gradient is the same as the slope (that is the rate of change). The gradient of a volcano tells how steep the volcano is. It is the ratio of the change in the height to the change in horizontal distance. The gradient is given by the formula:

Gradient = change in vertical distance or height / change in horizontal distance. Hence:

Gradient = (5340 feet - 4850 feet) / 2 miles

Gradient = 245 feet per mile

Puerto Rico, while not a US state, is a US territory.
