Question

A model car has a scale factor of 1/64. The diameter of a tire on the model is 0.43 inches. So, the diameter of the tire on an actual car must be inches. Your answer must be correct to one decimal place.

Answer 1

Answer:27.52 inches

Explanation:

Given

Scale factor
`(1)/(64)` i.e.

`\frac{\text{Model}}{\text{Prototype}}`

The diameter of the model tire is 0.43 inches

Scale factor =
`\frac{\text{dia. of model}}{\text{dia. of actual car}}`

`(1)/(64)=(0.43)/(D)\\D=64* 0.43=27.52\ \text{inches}`
