You either run 8 miles per hour or walk 4 miles per hour.  Write an equation to show the relationship between time ran and time walked during the 26.2 mile course and then graph the equation.   I tried to use 8X + 4Y = 26.2 but it did not work out.  If you could just help me get the right equation then I can do the graph and the following couple of problems which are all related to this equation.\r<BR>\n" );
