Question

select the correct answer.
choose the statement that best describes
the positions in the diagram:
there is a distance of 100 m
between position s and
position b.
there is a distance of 80 m
between position a and
position s.
there is a distance of 120 m
between position s and
position b.
there is a distance of 20 m
between position a and
position b.

Explanation:

Step1: Calculate distance between S and B

The coordinate of S is - 20 and of B is 80. Distance \(d=\vert80 - (-20)\vert=\vert80 + 20\vert = 100\) m.

Step2: Calculate distance between A and S

The coordinate of A is 0 and of S is - 20. Distance \(d=\vert0-(-20)\vert=\vert0 + 20\vert=20\) m.

Step3: Calculate distance between A and B

The coordinate of A is 0 and of B is 80. Distance \(d=\vert80 - 0\vert=80\) m.

Answer:

There is a distance of 100 m between position S and position B.
