Answer:
Aria's vertical distance from the top of the valley is less than 3 km when it traveled 3km along the trail
Explanation:
we are given
v(d) models Aria's vertical distance from the top of the valley (in kilometers)
after walking d kilometers along the trail
v(3) means d=3
so, it traveled 3km along the trail
v(d)=3 means Aria's vertical distance from the top of the valley is 3km
so,
![V(3)<3](https://img.qammunity.org/2020/formulas/mathematics/high-school/pvllrsxqku456z5e70cxqhmo5qzslzn8xs.png)
It means that
