**Extra Tip!** Notice that we added the labels feet/second to our answer. Why does this make sense?? The question tells us that *P(t)* *represents feet* and that *t is equal to seconds. *Another way to look at this question when applying it to the slope formula is to realize that we are finding the* change of feet* divided by the *change of seconds*. ____________________________________________________________________________________
