Answer:

It would take 70 minutes to fill 420 cartons of eggs.

Explanation:

Let's use ratios for this problem.

1 minute to fill 6 cartons of eggs can be displayed as a ratio:

#1:6#

To find out how long it would take to fill 420 cartons, we must divide 420 by 6.

#420/6=70#

If we multiply each side of our ratio by 70, we'll have our final answer:

#70 : 420#
