What is the slope of a road with a 7% grade?

Calculating the Slope of a Road with a 7% Grade

The slope of a road is a measure of its steepness, indicating the amount of vertical rise for a given horizontal distance. It is commonly expressed as a percentage or a ratio.

Understanding Road Grade

Road grade is a specific type of slope measurement that refers to the vertical rise in feet per 100 feet of horizontal distance. A 7% grade, for example, means that for every 100 feet of horizontal travel, the road ascends 7 feet vertically.

Calculating the Slope of a 7% Grade

To determine the slope of a road with a 7% grade, we can use the formula:

Slope = Vertical Rise / Horizontal Distance

In this case, the vertical rise is 7 feet, and the horizontal distance is 100 feet. Plugging these values into the formula, we get:

Slope = 7 feet / 100 feet

Slope = 0.07

Interpreting the Slope

The resulting value of 0.07 represents the slope of the road. Since it is less than 1, it indicates that the road has a moderate incline. A slope of 1 or greater would represent a steep incline.

Therefore, the slope of a road with a 7% grade is 0.07, indicating a moderate incline. This means that for every 100 feet of horizontal travel, the road rises 7 feet vertically.
