PLEASE HELP! I will medal and fan! I DONT WANT AN ANSWER, I WANT HELP!! Courtney reads around 110 words per minute. She procrastinated and now has less than a week to finish her reading assignment. If the book she needs to finish has another 820 pages left and each page has around 350 words, how many hours should she set aside to complete her assignment? I NEED TO SHOW MY WORK

    Look at this, if 1 page has 350 words, 820 pages means you multiply 820 by 350, then you will get the total number of words in 820 pages.

    Yep, thats the total number of words. Next I like to use some Physics knowledge in it, its simple just a formula. \[Speed=\frac{distance}{time}\] We know the speed = 100words/min Distance(interpreted as) = 287000words Therefore you get \[110=\frac{287000}{time}\]

    \[time=\frac{287000}{110}\] =2609minutes

    2609minutes divided by 60 to get the hours
