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

Explanation:

The function \(V(d)\) defines \(d\) as the distance walked along the trail, and \(V(d)\) as the vertical distance from the valley top. For \(V(3) < 3\), the input \(d=3\) means 3 km walked along the trail, and the output \(V(3) < 3\) means the vertical distance is less than 3 km.

Answer:

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