average rate=(change in height)/(change in time)

r=(4500-3700)/(4+12-12)

r=800/4

r=200 ft/hr

200 feet per hour.

Answer: 200 ft per hour

Explanation:

Given : You are hiking on a trail that leads to the top of a mountain.

At 12 P.M. you reach an elevation of 3700 feet. At 4 P.M. you reach an elevation of 4500 feet.

The formula for the mean hourly change in elevation is :-


\frac{\text{Change in elevation}}{\text{Time in hours}}

From the given information, the change in elevation=4500 ft-3700 ft= 800 ft

Time taken = 4 hours [From 12 pm to 4 pm]

Now, Mean hourly change in elevation=
(800)/(4)=200

Hence, the mean hourly change in elevation = 200 ft
