Answer:
12.7 units
Step-by-step explanation:
Formula to get the distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
d = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
From the picture attached,
Sherry is at the origin(0, 0) and going to the top (12, 4)
Distance between these points will be,
d = [tex]\sqrt{(12-0)^2+(4-0)^2}[/tex]
d = [tex]\sqrt{160}[/tex]
d = [tex]4\sqrt{10}[/tex]
≈ 12.7 units
Therefore, Sherry has to travel 12.7 units on the ramp.
