Question

A scooter is 3 1/2 feet long find the length of a scale model of the scooter if the scale is 1 inch =3/4

Answer 1

To determine the length of a scale model of the scooter;

$Scale\text{ factor =}\frac{length\text{ }of\text{ }model}{length\text{ of scooter}}$$Scale\text{ factor=}\frac{1}{\frac{3}{4}}$$Length\text{ of scooter = 3}\frac{1}{2}$$Let\text{ the length of the model be }\omega$

Let me find the length of the model now;

$Scale\text{ factor =}\frac{length\text{ }of\text{ }model}{length\text{ of scooter}}$$\frac{1}{0.75}=\frac{\omega}{3.5}$$\begin{gathered} 0.75\omega=3.5 \\ \omega=\frac{3.5}{0.75} \end{gathered}$$\omega=4.6666667=4\frac{2}{3}ft$$The\text{ answer is 4}\frac{2}{3}ft$
