Question

This graph shows the distance that a robot walks. What is the rate of change of the robot's location?

Answer 1

The rate of change, m, is;

`\begin{gathered} m=(d_2-d_1)/(t_2-t_1) \\ \\ \text{ Where }d=distance,t=time \end{gathered}`

Thus;

`\begin{gathered} (1,10),(3,30) \\ \\ m=(30-10)/(3-1) \\ \\ m=(20)/(2) \\ \\ m=10 \end{gathered}`

ANSWER: (D) 10 feet per minute
