Question

You are hiking on a trail that leads down from the top of a mountain. At 11 A.M. You are at an elevation of 5400 feet. At 3 P.M. You are at an elevation of 3800 feet. What is your mean hourly change in elevation?

Answer 1

Explanation:

You hiked 5400 - 3800 = 1600 feet in 4 hours so the mean change is 1600 / 4 = 400 ft/hour.
