Let's say that Point A is Chipotle, and Karl and Kyle both have to walk to their houses from Chipotle. If Karl goes two blocks West and 5 blocks South to his house, and Kyle goes two blocks east from Chipotle and 5 blocks North, how far apart are the two houses? Well to find out, you have to use the distance formula: [math]_{ }\surd\left(x_1-x_2\right)^2+\left(y_1-y_2\right)^2[/math] So plug in the two coordinates of the houses (Point E and Point C). When you are done, you should end up with the answer of 10.8 blocks.
