Question

erica walked down a trail into a valley. v(d) models ericas vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail. what does the statement v(2)=t mean? choose 1 answer: a ericas vertical distance from the top of the valley was the same after she had walked 2 km and after she had walked t kilometers. b after she had walked 2 km along the trail, ericas vertical distance from the top of the valley was equal to t kilometers. c after she had walked t kilometers along the trail, ericas vertical distance from the top of the valley was equal to 2 km

Explanation:

The function $V(d)$ gives the vertical distance from the top of the valley based on the distance $d$ walked along the trail. When $d = 2$, $V(2)$ represents the vertical distance after walking 2 km, and it is equal to $T$.

Answer:

B. After she had walked 2 km along the trail, Erica's vertical distance from the top of the valley was equal to $T$ kilometers.
