Let r be the rate at which Dr. Nelms rode on the second leg. Then the first leg's rate would be r+4. So:
\n" ); document.write( "35/(r+4)+22/r=2
\n" ); document.write( "35r+22(r+4)=2rē+8r
\n" ); document.write( "2rē-49r-88=0
\n" ); document.write( "r=26.18 or -1.68
\n" ); document.write( "Throwing out the negative result, we get the first part of the trip traveled at 30.18 mph, and the second at 26.18. ☺☺☺☺
\n" ); document.write( " \n" ); document.write( "
