Question

Carlos made a scale model of a local bridge. The model spans 6 inches; the actual bridge spans

Answer 1

$\boldsymbol{\mathbf{Answer}}$

$\boldsymbol{\mathbf{Scale\,factor \,of\, the \,model \,is\, 0.01\,}}$

$\boldsymbol{\mathbf{Step-by-step\,explanation}}$

Carlo's scaled bridge model spans 6 inch.

Actual bridge spans  50 feet.

We know that,

1 feet = 12 inches.

i.e  = ${12}\times{50}$

actual bridge span = 600 inches.

Scale factor of the model is,

= $\frac{6}{600}$

$\boldsymbol{\mathbf{Scale factor = 0.01}}$

That means the scale model is 0.01 time smaller than actual model.
