Answer: 7 percent
Explanation:
To find the grade of a road, we use the formula:
Grade = Rise / Run
where "Rise" represents the vertical change or elevation, and "Run" represents the horizontal distance.
In this case, the road rises 14 feet for every 200 horizontal feet.
Therefore, the grade of the road is:
Grade = 14 feet / 200 feet
Simplifying the fraction by dividing both the numerator and denominator by 2, we get:
Grade = 7 feet / 100 feet
Now, we can express the grade as a decimal by dividing 7 by 100:
Grade = 0.07
To express the grade as a percentage, we multiply the decimal by 100:
Grade = 0.07 * 100
Grade = 7%
Therefore, the grade of the road is 7%.
