Question 1164012
<font face="Times New Roman" size="+2">


The distance traveled at some rate plus three miles per hour for four hours is the same as the distance traveled at the same rate minus three miles per hour, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  10(r\,-\,3)\ =\ 4(r\,+\,3)]


Solve for *[tex \Large r], then calculate *[tex \Large 20(r\ -\ 3)]

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