Question

The table below gives the dimensions of a bridge and a scale model of the bridge.

Answer 1

Answer:

Scale factor = $\frac{1}{5}$

Step-by-step explanation:

Formula for the scale factor is,

Scale factor = $\frac{\text{Dimension of the model}}{\text{Dimension of the original}}$

                    = $\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}$

                    = $\frac{\text{Width of the model}}{\text{Width of the bridge}}$

                    = $\frac{7}{35}$

                    = $\frac{1}{5}$

Therefore, scale factor of the model to the real bridge = $\frac{1}{5}$
