Answer:

9. $\frac{1}{10}$ fraction.

10. $\frac{3}{10}$ fraction.

Step-by-step explanation:

In the given table, we get, Andrea hiked $\frac{2}{5}$ of the total trail, Jon hiked $\frac{1}{2}$ of the total trail and Callie hiked $\frac{4}{5}$ of the total trail.

9. Therefore, Jon hiked $(\frac{1}{2} - \frac{2}{5}) = \frac{5 - 4}{10} = \frac{1}{10}$ fraction than Andrea hiked.

10. Therefore, Callie hiked $(\frac{4}{5} - \frac{1}{2}) = \frac{8 - 5}{10} = \frac{3}{10}$ fraction than Jon hiked. (Answer)

Answer:

(-1,-0.5)

Step-by-step explanation:

We can see from our given graph that Fernando is at point (-4,-2) and Maria is at point (4,2). They will meet at the fountain located somewhere between them.

We can see that fountain will divide our given line segment internally, so we will use section formula, when a point internally divides a segment in ratio m:n.

$[\frac{m*x_2+n*x_1}{m+n},\frac{m*y_2+n*y_1}{m+n}]$
