Average rate of change =
(change in height during some time) / (length of time for the change).
Change in height = (700 feet  400 feet) = 300 feet
Time for the change = (6 hours  2 hours) = 4 hours
Average rate of change = (300 feet) / (4 hours) = 75 feet per hour

Answer:
75 feet per hour is the rate of change in altitude.
Stepbystep explanation:
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 400 feet.
We have to determine the average rate of change in altitude.
We know rate of change in altitude = [tex]\frac{\text{(Change in altitude)}}{\text{Change in time}}[/tex]
= [tex]\frac{700400}{62}[/tex]
= [tex]\frac{300}{4}[/tex]
= 75 feet per hour
Therefore, 75 feet per hour is the rate of change in altitude.
