Question 1164014
<font face="Times New Roman" size="+2">


He traveled *[tex \Large d] miles at *[tex \Large 55\text{ mph}].  Then he traveled *[tex \Large 234.5\,-\,d] miles at *[tex \Large 49\text{ mph}].  The two parts of the trip took 4.5 hours total, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{d}{55}\,+\,\frac{234.5\,-\,d}{49}\ =\ 4.5]


Solve for *[tex \Large d], then calculate *[tex \Large 234.5\ -\ d]

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