A climber is on a hike. After 4 hours he is at an altitude of 800 feet. After 12
hours, he is at an altitude of 1400 feet. What is the average rate of change? *

First Problem: 200 ft/hour Second Problem: 3 ft/hour

Step-by-step explanation:

R = D/T

So, 800/4=200

We will check if the rate matches for the second example rate:

1400/12=200. It does, so we know we are correct

Problem 2:

R = D/T

90/30=3

Hope it helps.
