Question

While on a mountain hike, you see a sign posting that you are at an elevation of 130 ft You arrive at another sign 10

minutes later that says you are at an elevation of 240 ft
What was your average rate of change of elevation? Round your answer to the nearest whole number, if necessary.

Answer 1

11 feet every minute

Explanation:

We first need to figure out how far you traveled up.

240 - 130 = 110

Now, we can solve for the average rate of elevation.

If you travel 110 feet in 10 minutes, we can do this equation:

110 ÷ 10 = 11

The average change of elevation, every minute, was 11.
