Question da09d

$D = \left(45 \text{mi"/"h}\right) T$

Explanation:

The fact that it is traveling at a constant $45 \text{mi"/"h}$ tells that it travels a distance $45$ $\text{mi}$ in $1$ $\text{h}$.

This can be represented as

$45 \text{mi"/"h} = \frac{D}{T}$

rearranging for the distance, $D$, we have the function

color(red)(D = (45"mi"/"h")T#

You can use this function to find the distance traveled (in miles) after a time $T$ (in hours).
