Stephen is tracking how many words per minute (wpm) he reads for reading class. He is now at 112 wpm, and each week he hopes to increase his speed by 8 words per minute.Equation: w = 112 + 8tt = time (weeks)w = wpmHow many weeks will it take Stephen to reach 171 wpm?

Answer: 8 weeksStep-by-step explanation:Given : Stephen is tracking how many words per minute (wpm) he reads for reading class.Equation: [tex]w = 112 + 8t[/tex], where t = time (weeks)  and w = wpm .Then, the equation to find number of weeks (w), it will take Stephen to reach  171 wpm is given by :-[tex]171=112+8t\\\\\Rightarrow\ 8t=171-112\\\\\Rightarrow\ 8t=59\\\\\Rightarrow\ t=\dfrac{59}{8}=7.375\approx8[/tex]Hence it will take about 8 weeks Stephen  to reach  171 wpm.
