Problem
A small public park has its main gate G located at the southern edge. A wooden bench B is placed 20m north of the gate, and a marble statue S is installed 35m south of the bench along the same straight path.
Answer the following questions about the positions of these objects.
(i) Define the term "reference point" as used in describing the position of an object.
(ii) Taking the gate G as the reference point and the northward direction as positive, state the positions (with sign and unit) of the bench B and the statue S.
(iii) If the statue S is now chosen as the reference point while the positive direction remains northward, state the positions of the bench B and the gate G relative to the statue.
