Answer:
22.5
Explanation:
A car moves 12 on north so it will a vertical length of 12.
It also moves 19 km east so it will have a horizontal length of 19.
Since north and south have different vectors, or different slope they will form perpendicular lines so it forms a right angle.
Since it has a right angle and it ask for displacement (which is the distance between the two directions) we use the pythagorean theorem.

where r is displacement and a and b are the vectors.




which is about 22.5

In most cases, paper books have more obvious topography than onscreen text. An open paperback presents a reader with two clearly defined domains—the left and right pages—and a total of eight corners with which to orient oneself. A reader can focus on a single page of a paper book without losing sight of the whole text: one can see where the book begins and ends and where one page is in relation to those borders. One can even feel the thickness of the pages read in one hand and pages to be read in the other. Turning the pages of a paper book is like leaving one footprint after another on the trail—there's a rhythm to it and a visible record of how far one has traveled. All these features not only make text in a paper book easily navigable, they also make it easier to form a coherent mental map of the text.
