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


Not enough information given to solve this problem except to express the answer in terms of the original speed or the elapsed time for the slow leg of the trip.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2r\ +\ t(r\ -\ 10)\ =\ 152]


If you made an error posting the problem and meant to include the number of hours for the slow portion of the trip, substitute that number for *[tex \Large t] and solve for *[tex \Large r]
