Question 461805
<font face="Times New Roman" size="+2">


If they are 500 miles apart after 5 hours, then their speed relative to each other must have been 100 miles per hour.  Since they are traveling in opposite directions, their individual speeds must sum to their relative speed.


So if *[tex \Large x] represents the slower car's speed then *[tex \Large x\ +\ 10] must represent the faster car's speed, and:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ x\ +\ 10\ =\ 100]


Solve for *[tex \Large x] and then calculate *[tex \Large x\ +\ 10]


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