[tex]\boldsymbol{\mathbf{Width \,of \,scale\, model \,is\, 4.5 \,cm} }[/tex]
[tex]\boldsymbol{\mathbf{Step-by-step \,explanation}}[/tex]
The Actual size of locomotive are,
Tall = T = 5 m = 500 cm
Long = L = 27 m = 2700 cm
Width = W = 3 m = 300 cm
The scale model sizes are,
Tall = T = t cm
Long = L = 40.5 cm
Width = W = w cm
Scale factor of the model is,
= [tex]{40.5}\times{2700}[/tex]
[tex]\boldsymbol{Scale factor = 0.015}[/tex]
That means the scale model is 0.015 time smaller than actual model.b
Width of scale model is,
= [tex]{300}\times{0.015}[/tex]
= [tex]\boldsymbol{\mathbf{4.5\,cm}}[/tex]
