1) Examining the tables we can gather the following points
(t, d)
(10, 7)
(15, 10.5)
(20, 14)
2) So we can see that there is a proportional relationship if we divide the time by the distance. So we can write the constant k as:
[tex]\begin{gathered} k=\frac{t}{d} \\ k=\frac{10}{7}=\frac{15}{10.5}=\frac{20}{14} \\ t=\frac{10}{7}d \end{gathered}[/tex]
3) So the equation that describes the relationship between the time and the distance is:
[tex]t=\frac{10}{7}d[/tex]
