the chart shows danielas run through her race. what is her velocity? 1.5 m/s 2 m/s 2.5 m/s 5 m/s

Explanation:

Step1: Identify two points on the line

Let's take the points (0, 5) and (10, 25).

Step2: Use the velocity formula $v=\frac{\Delta x}{\Delta t}$

$\Delta x=x_2 - x_1=25 - 5 = 20$ m, $\Delta t=t_2 - t_1=10-0 = 10$ s. Then $v=\frac{20}{10}=2$ m/s.

Answer:

2 m/s
