As part of your job as a quality-control inspector in a factory, you can check 16 parts in 3 minutes. How long will it take you to check 80 parts?

Answer :

16 x 5= 80 so it would take 15 minutes :)
just divide 80 by16 and you get 5. you multiply 5 by 3 and get 15 so the answer should be 15 minutes.
