Pls help I don’t understand any of it, I just need 7b, c, and d. Thank you!!!

Average velocity's formula: [tex]A_v=\frac{Td}{Tt}[/tex]; where Td is the total distance covered by the robot and Tt is the total time used to cover that distance. Substitute the values in the formula and calculate:

[tex]A_v=\frac{30m}{10s}=3m/s[/tex]

Hence, the average velocity on the graph will consist on a line whose slope is 3. Another easier method to mark the average velocity of the robot is to just make a line that starts on the first point of the graph and finishes on the last point. Check attached image 2 to see the result.

Part c.

To calculate the answer for this question, use the same formula presented on "Part b" and substitute by the correct values.

[tex]A_v=\frac{25m-17m}{8s-6s}=4m/s[/tex].

Part d.

We already solved this in "Part b". Write it again with more detail for this part.

[tex]A_v=\frac{P_2-P_1}{t_2-t_1}[/tex]; where [tex]P_2[/tex] and [tex]P_1[/tex] are the final position, and initial position, respectively. Also, [tex]t_2[/tex] and [tex]t_1[/tex] are the final time, and initial time, respectively.

[tex]A_v=\frac{P_2-P_1}{t_2-t_1}=\frac{30m-0m}{10s-0s}=3m/s[/tex]
