So, she has 3hrs to grade all papers, for 35 students.. alrite.
the first 5, she does them in 30minutes.. what's the speed rate? well, 5/30 or 1/6
now, she has still 2 hours and a half, or 150 minutes, to do the remaining 30 papers... she has to work at a rate of 30/150 then... which is 1/5 simplified.
now if we take 1/6 as the 100%, what is 1/5 in percentage then?
![\bf \begin{array}{ccllll} rate&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ \frac{1}{6}&100\\\\ \frac{1}{5}&x \end{array}\implies \cfrac{\frac{1}{6}}{\frac{1}{5}}=\cfrac{100}{x}\implies \cfrac{1}{6}\cdot \cfrac{5}{1}=\cfrac{100}{x}\implies \cfrac{5}{6}=\cfrac{100}{x} \\\\\\ x=\cfrac{6\cdot 100}{5}\implies x=120](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bccllll%7D%0Arate%26%5C%25%5C%5C%0A%5Ctext%7B%5Ctextemdash%5Ctextemdash%5Ctextemdash%7D%26%5Ctext%7B%5Ctextemdash%5Ctextemdash%5Ctextemdash%7D%5C%5C%0A%5Cfrac%7B1%7D%7B6%7D%26100%5C%5C%5C%5C%0A%5Cfrac%7B1%7D%7B5%7D%26x%0A%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B%5Cfrac%7B1%7D%7B6%7D%7D%7B%5Cfrac%7B1%7D%7B5%7D%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%20%5Ccfrac%7B1%7D%7B6%7D%5Ccdot%20%5Ccfrac%7B5%7D%7B1%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%5Cimplies%20%5Ccfrac%7B5%7D%7B6%7D%3D%5Ccfrac%7B100%7D%7Bx%7D%0A%5C%5C%5C%5C%5C%5C%0Ax%3D%5Ccfrac%7B6%5Ccdot%20100%7D%7B5%7D%5Cimplies%20x%3D120)
so 1/5 is 120% in relation to 1/6... meaning the rate of 1/5 she needs to move through, namely 1 paper every 5 minutes, is 20% faster than 1/6.
