Using the distance between two points, the distance between the start and the end of the parade is of 13 units.
What is the distance between two points?
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
For this problem, the points are (3, -4) and (3, 9), hence the distance is given by:
[tex]D = \sqrt{(3 - 3)^2+(9 - (-4))^2} = \sqrt{13^2} = 13[/tex]
The distance between the start and the end of the parade is of 13 units.
