Answer 2

Answer:

$120\ cars$

Step-by-step 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

$5*60=300\ minutes$

$\frac{14}{35}\frac{cars}{minutes} =\frac{x}{300}\frac{cars}{minutes}\\ \\x=300*14/35\\ \\x=120\ cars$
