Question 188190
<font face="Goudy Old Style" size="+2">

If the man walked at 3 mph for 2 hours, then he would have travelled 6 miles <i>before</i> he stopped to rest.  So if the total distance of the walk is <i>d</i>, then the distance walked after he rested must be <i>d</i> - 6.  If <i>t</i> is the time walked after the rest and the rate, <i>r</i>, is still 3 mph, then the equation


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ d - 6 = 3t]


describes the relationship between <i>d</i> and <i>t</i>.
