Question

A city has streets that run north and south and avenues that run east and west, all equally spaced. Streets and avenues are numbered sequentially, as shown in the figure. The *walking* distance between points *A* and *B* is 7 blocks—that is, 3 blocks east and 4 blocks north. To find the *straight*-*line* distance *d*, we must use the Distance Formula.

(a) Find the straight-line distance (in blocks) between *A* and *B*.

b) Find the walking distance and the straight-line distance between the corner of 4th St. and 2nd Ave. and the corner of 12th St. and 17th Ave.

(c) What must be true about the points *P* and *Q* if the walking distance between *P* and *Q* equals the straight-line distance between *P* and *Q*?

-Points *P* and *Q* must be on the same street and the same avenue.

-Points *P* and *Q* must either be on the same street or the same avenue. -Points *P* and *Q* must be on different streets and different avenues.

-Points *P* and *Q* must either be on different streets or different avenues.

-There is not enough information.
