Stephanie can type around 70 words per minute. She has less than a week to type her final research paper. If the paper has to be at least 15 pages long and each page has about 350 words, how many hours should Stephanie set aside to type her assignment? Show your work to receive full credit

The total amount of words in 15 pages will be

350 * 15 = 5,250

She can type 70 words per minute, now how about per hour? Each hour has 60 minutes so we calculate to find out the total amount of words she can type per hour.

This will be 70 * 60 = 4,200 words

Now we calculate how many hours it will take to type 5, 250 words.

1 hour = 4,200

x = 5,250

where x is the time in hours needed to type 5,250 words.

We cross multiply the equation:

4,200 * x = 5,250 * 1

4,200x = 5,250

x = 5,250/4,200

x = 1.25

She will need 1 and a quarter hours to type her paper.
