Answer:
13.5 minutes
Step-by-step explanation:
to solve this problem, you have to find how many words she can type per minute, so you would divide 128 by 3. then, you take how many words she types per minute and divide 576 by that number to see how many minutes it takes to get to 576 words.
it'll look like this:
128 / 3 = 42 2/3
576 / 42.67 = 13.5
