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=}(1)/((3)/(4))`
`Length\text{ of scooter = 3}(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}}`
`(1)/(0.75)=(\omega)/(3.5)`
`\begin{gathered} 0.75\omega=3.5 \\ \omega=(3.5)/(0.75) \end{gathered}`
`\omega=4.6666667=4(2)/(3)ft`
`The\text{ answer is 4}(2)/(3)ft`
