Question 1122393
<font face="Times New Roman" size="+2">


1.  *[tex \LARGE t_R(x)\ =\ \frac{2}{x}\ +\ \frac{8}{x\ +\ 1}]


2.  *[tex \LARGE \frac{2}{x}\ +\ \frac{8}{x\ +\ 1}\ +\ \frac{2}{3}\ =\ \frac{10}{x}]


Note that 40 minutes is *[tex \LARGE \frac{2}{3}] hour.  I'll let you do the reduction (hint, multiply through by *[tex \LARGE 3\(x^2\ +\ x\)]) and the solution of part 3 yourself.

My calculator said it, I believe it, that settles it
