Question

aria walked down a trail into a valley. v(d) models arias vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail. what does the statement v(3) < 3 mean? choose 1 answer: a when aria had walked 3 km along the trail, her vertical distance from the top of the valley was less than 3 km. b the time it took aria to walk 3 km is shorter than the time it took her to be at a vertical distance of 3 km. c when arias vertical distance from the top of the valley was 3 km, the distance she had walked along the trail was less than 3 km.

Explanation:

The function $V(d)$ gives Aria's vertical distance from the top of the valley when she has walked $d$ kilometers along the trail. In $V(3)$, $d = 3$ (she has walked 3 km along the trail), and $V(3)$ is her vertical distance from the top of the valley at that point. The inequality $V(3)<3$ means this vertical - distance value is less than 3 km.

Answer:

A. When Aria had walked 3 km along the trail, her vertical distance from the top of the valley was less than 3 km.
