Calculation:

Let, the space to be left between each poster be x ft.

Hence, total space according to the figure is 2x ft.

From the above figure, the following equation can be generated.

  $2x+12=15$

Now,

  $\begin{array}{l}\Rightarrow 2x+12=15\\ \Rightarrow 2x=3\\ \Rightarrow x=\frac{3}{2}\\ \Rightarrow x=1.5\end{array}$

Conclusion:

Hence, the space required to be left between each posters is 1.5 ft.
