We have rate times time = distance.
\n" ); document.write( "Let x be the amount of time he walked.
\n" ); document.write( "Thus 8-x is the time he rode.
\n" ); document.write( "Then we can write
\n" ); document.write( "4x+15(8-x)=76
\n" ); document.write( "4x + 120 - 15x = 76
\n" ); document.write( "-11x = -44
\n" ); document.write( "x = 4 hours
\n" ); document.write( "
\n" );
