Answer 2

`120\ cars`

Explanation:

we know that

The ace motor co. can assemble
`14` cars in
`35` minutes

so

by proportion

Find how many cars can they assemble in
`5` hours

First convert
`5` hours to minutes

`5*60=300\ minutes`

`(14)/(35)(cars)/(minutes) =(x)/(300)(cars)/(minutes)\\ \\x=300*14/35\\ \\x=120\ cars`
