McGill types 270 words in six minutes his paper is 630 words if he keeps waving at the same rate and how many more minutes when
Delicious77 [7]

Answer:

8 more minutes.

I think the perfect version in your question is:

<em>McGill types 270 words in six minutes his paper is 630 words if he keeps waving at the same rate and how many more minutes when McGill finish typing his paper</em>

Given that:

  • 270 words in six minutes <=> 1 minute = \frac{270}{6} = 45 words
  • His paper is 630 words

So, the total minutes he needs to finish the paper if  he keeps waving at the same rate is:

\frac{The number of words}{Number of words written in one minute}

= \frac{630}{45}

= 14 minutes.

So he needs 14 minutes to finish writing the paper, but he wrote 270 words in 6 minutes already, so it will take him 14-6 = 8 more minutes.

Hope it will find you well!
