**Page 159: Introductory page**

**Pages 160-161: It would be a bit too intense… // Story #1 is about a galloping horse.**

**Pages 162-163: One way to calculate average velocity… // Fortunately, we can find this limit…**

**Pages 164-165: But in addition to calculating average velocity… // We just covered two different ways…**

**Pages 166-167: Story #2 starts when we take two basic facts about circles… // We can use the tools from Chapter 7…**

**Pages 168-169: The next part of story #2 is about rings. // But another way to calculate the area of a ring…**

**Pages 170-171: Of course, these two ways to calculate area… // This story about area isn’t a proof…**

**Page 172: And there’s a bonus…**
