10. It takes a machine 12 minutes to fill 200 bottles of soda. At this rate, how many
minutes will it take the machine to fill 500 bottles of soda?

Respuesta :

Answer:

30 minutes.

Step-by-step explanation:

Because it takes 12 minutes to fill 200 bottles of soda. Add 12 to 12 again and you'll get 24. In 24 minutes, it'll be 400 bottles. Half of 12 is 6 and half of 200 is 100. So that add 6 minutes (which is a 100 bottles) and you'll get 500 bottles of soda in 30 minutes.

Bottles per minute = 200/12
16.6666(4decimal places)
Minutes taken to fill 500bottles=500/16.6666
=30.0(3 significant figures)
