Answer:
1.33 cm/s
Step-by-step explanation:
The line is going from point (0;0) to point (12;16), the proportional relationship between these points refer to the slope of the line, which can be found with this expression:
[tex]m=\frac{\Delta y}{\Delta x}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Replacing all values we have:
[tex]m=\frac{16-0}{12-0}=\frac{16}{12}=1.33[/tex]
Therefore the relation shown in the graph is represented by 1.33 cm/s, which refers to the constant speed developed by the object.
