Victoria is at an elevation of 150 feet. She hikes down to an elevation of 120 feet in 40 minutes.
Then she hikes down to an
elevation of 100 feet in 30 minutes.

What is her average rate of descent, in feet per minute, from 150 feet to 120 feet?

Respuesta :

The Victoria's average rate of descent by hiking down from an elevation of 150 feet to an elevation of 120 feet in 40 minutes is equal to 0.75 feet per minute.

How to determine the average rate of descent of a hiker

Geometrically speaking, the average rate of descent (r), in feet per minute, is represented by a secant line, which represents in this case the change in elevation (Δz), in feet, divided by the change in time (Δt). A mathematical description of the formula is shown below:

r = Δz/Δt     (1)

If we know that Δz = 30 ft and Δt = 40 min, then the average rate of descent is:

r = 30 ft/40 min = 0.75 ft/min

The Victoria's average rate of descent by hiking down from an elevation of 150 feet to an elevation of 120 feet in 40 minutes is equal to 0.75 feet per minute. [tex]\blacksquare[/tex]
