Question

Clara and her grandfather are putting together a scale model of an actual car. A part that is m inches long on the actual car will be 0.04m inches on the model car. The door of the actual car is 40 inches long. How long is the door on the model car?

Answer 1

1.6m

Explanation:

let 'x' = door length on model car

1 meter is to .04 meters as 40 is to x

`(1)/(.04)` =
`(40)/(x)`

cross-multiply to solve for 'x'

x = 40 multiplied by .04, which is 1.6
