Question

A climber is on a hike. after 2 hours he is at an altitude of 400 feet. After 6 hours, he is at an altitude of of 700 feet. What is the average rate of change?

Answer 1

To do this, we need to use the slope formula. This is the slope formula:

(y2-y1)/(x2-x1)

This gives the average rate of change when the values are plugged in.

(700-400)/(6-2)

300/4

75

Don’t forget labels!

75 ft/hr
