Answer 1

The percent grade change of the road going to Mount Pierce is approximately 4.5%

Step-by-step explanation:

To find the percent grade change of the road going to Mount Pierce in New Hampshire, we can use the formula: percent change = 100 * (rise / run). In this case, the rise is the change in elevation (from 1000 feet to 1950 feet) and the run is the distance (4 miles or 21120 feet).

Using the formula, we have:

Percent change = 100 * ((1950 - 1000) / 21120)

Percent change = 100 * (950 / 21120)

Percent change ≈ 4.5%

Therefore, the percent grade change of the road going to Mount Pierce is approximately 4.5%. The closest answer choice is option A, 15%, which is not correct. The correct answer is None of the above.
