Question 408079

If you have two questions, go back and make two posts.  Read the instructions, "One question per post"


Let *[tex \Large x] represent the walking rate.  Then *[tex \Large 4x] is the running rate.


Since distance equals rate times time, the distance walked must be *[tex \Large 3x] and the distance ran must be *[tex \Large 2\ \cdot\ 4x].  The sum of these distances is 55, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 3x\ +\ 8x\ =\ 55]


Solve for *[tex \Large x]

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
