Question

Write an equation to describe the relationship between t the time and d distance

Answer 1

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:

`\begin{gathered} k=(t)/(d) \\ k=(10)/(7)=(15)/(10.5)=(20)/(14) \\ t=(10)/(7)d \end{gathered}`

3) So the equation that describes the relationship between the time and the distance is:

`t=(10)/(7)d`
