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

Is 30/12 and 40/16 equivalent?
Flura [38]
30/12 in simplest form is 5/2 (cause 6 * 5 = 30 and 6 * 2 = 12)
40/16 in simplest form is 5/2 (cause 8 * 2 = 16 and 8 * 5 =40)
so yes they're equivalent;
30/12 = 40/16
Hope that helps :D have a nice day!
