Lexus skateboards from his house to school 4 miles away. It takes him 20 minutes.

RoseWind [281]

Answer:

$\displaystyle m = \frac{1}{5}\cdot t$

Step-by-step explanation:

<u>Proportional Model</u>

The number of miles m that Lexus can skateboard in t minutes can be modeled by:

m = kt

It's given that Lexus skateboard from his house to school for a distance of m=4 miles in t=20 minutes.

Substituting:

4 = k.20

Dividing by 20

$k=\frac{4}{20}$

Simplifying:

$k=\frac{1}{5}$

This produces the model

$\displaystyle m = \frac{1}{5}\cdot t$
