Answer

Explanation:

Step1: Define forward and backward movements

Let forward be positive and backward be negative. Initial position is 0. First - move: + 18 cm, second - move: - 6 cm, third - move: - 12 cm.

Step2: Calculate the displacement

Displacement (d=0 + 18-6 - 12). [ \begin{align*} d&=18-(6 + 12)\ &=18 - 18\ &=0 \end{align*} ]

Answer:

0
