A hiker is walking down a mountain. She walked 5978 feet in 17 minutes. In that time she descended 1024 feet feom the top of the mountain. She then walked 3927 feet in 7 minutes. In that time she descended 500 more feet. Express the average rate of change in altitude of the hiker from her starting point to her ending point as unit rate

63.5 ft/min

Step-by-step explanation:

Given that:

A hiker is walking down a mountain.

For the first case:

She descended 1024 feet from the top of the mountain in 17 minutes after walking for 5978 feet.

For the second case:

She descended 500 more feet from the top of the mountain in 7 minutes after walking for 3927 feet.

Thus; the average rate of change in altitude of the hiker from her starting point to her ending point can be expressed as:

63.5 ft/min
