Answer: B) is the right answer→the distance between points a and b is equal to the distance between points b and c.
Step-by-step explanation:
As Kerry drew a number line starting at 0, point a, and ending at 1, point c and halfway between points a and c, he added point b.
.⇒ab=1/2 of ac and bc= 1/2 of ac or b is the mid point of line segment ac.
⇒ ab=bc(∵things which are equal to the same thing are equal to one another....→Euclid's first postulate)
Therefore, option B) the distance between points a and b is equal to the distance between points b and c is correct.
