A hiker is at a height of 700 meters and begins her descent. She descends at a rate of 13 m/min. Which function rule describes the climber's height of elevation after t minutes?

h = 700 - 13t

Step-by-step explanation:

The hiker is at a height of 700 meters and begins to descend.

She is descending 13 meters per minute rate.

Therefore, after t minutes she will descend by 13t meters.

So, finally, the elevation of the hiker after t minutes will be (700 - 13t)

If we represent h as the elevation of the hiker after t minutes,

then h = 700 - 13t is the function which describes the climber's height of elevation after t minutes. (Answer)
