The steepness of a road is called its grade. The higher the grade, the steeper the road is. For example, an interstate highway is considered out of standard if its grade exceeds 7%. Interpret a grade of 7% in terms of slope. Use feet to explain the meaning for a driver.

A grade of 7% = 7 / 100 ;

This means that the elevation or vertical heighy of the interstate highway changes 7 feets for every 100 feets of horizontal distance moved

Step-by-step explanation:

Given that :

A road has a grade of 7%. This means that the slope of the of the highway is 7%. The slope is the proportion of rise and run. Hence the change in vertical distance with horizontal distance moved.

A grade of 7% = 7 / 100 ;

This means that the elevation or vertical heighy of the interstate highway changes 7 feets for every 100 feets of horizontal distance moved
