3 spiders eat 3 little flies in 3 minutes, how long will one one hundred spiders eat one one hundred flies?

Question

Please help me answer this question it's worth an A for my class. Thank you!~

Answer 1

This means one spider eats one fly in 3 minutes.
(It takes three spiders to eat three in the same 3 minutes.)

So it takes a spider three minutes to eat a fly.
One hundred spiders eat a hundred flies - that's one fly per spider. So it still takes three minutes.

Answer 2

it will take 100 minutes
