CHAPTER ONE
1. (a) The story in (a) matches Graph (IV), in which the person forgot her books and had to retu
home.
(b) The story in (b) matches Graph (II), the flat tire story. Note the long period of
time during which the distance from home did not change (the horizontal
part).
(c) The story in (c) matches Graph (III), in which the person started calmly but sped up later.
The first graph (I) does not match any of the given stories. In this picture, the
person keeps going away from home, but his speed decreases as time passes. So a
story for this might be: I started walking to school at a good pace, but since I stayed
up all night studying calculus, I got more and more tired the farther I walked.
