Question

Example 2: A Real World Example

Maria decides to take a walk along Central Avenue to purchase a book at the bookstore. On her way, she passes the
Furry Friends Pet Shop and goes in to look for a new leash for her dog. Furry Friends Pet Shop is seven blocks west of the
bookstore. She leaves Furry Friends Pet Shop and walks toward the bookstore to look at some books. After she leaves
the bookstore, she heads east for seven blocks and stops at Ray's Pet Shop to see if she can find a new leash at a better
price. Which location, if any, is the farthest from Maria while she is at the bookstore?
Determine an appropriate scale, and model the situation on the number line below.
HHHHHHHH

Answer 1

Both pet stores are an equal distance away from the book store.

East and West are opposites and she has to go 7 in each direction (from the bookstore) to reach each pet store
