Question

It takes Winnie 10 minutes to type and spell check 6 pages of a manuscript. Find how long it takes her to type and spell check 27 pages. Round answers to the nearest whole number if necessary.

Answer 1

Let's calculate the rate of minutes per page and then multiply that by 27

rate:

$\frac{10}{6}=\frac{5}{3}=1.67$

time to type 27 pages:

$\frac{10}{6}\cdot27=45$

Thus, Winnie takes 45 minutes to type and spell check 27 pages
