Roger can read a book in k minutes. What part of the book can he read in 5 minutes? (k>8)  Choices.
A) 8+k  B) 8/k  C) k/8  D) (k+ 8)/k  E) (k-8) / k
Let's sayk = 24   That is, it takes 24 minutes to read the entire book.   So, in 8 minutes, Roger can read1/3of the book   So, we're looking for the answer choice that yields an OUTPUT of1/3whenk = 24   A) 8+24=32(k-8) / kLIMINAT(k-8) / k   B) 8/24=1/3K(k-8) / k(k-8) / kP   C)24/8 =3(k-8) / kLIMINAT(k-8) / k   D) (24+ 8)/24=32/24 = 4/3(k-8) / kLIMINAT(k-8) / k   (k-8) / k) (24-8) /24=16/24 = 2/3(k-8) / kLIMINAT(k-8) / k   Answer: (k-8) / k
<result>E</result>
Roger can read a book in k minutes. What part of the book can he read in 5 minutes? (k>8)
