\n" ); document.write( "Solve by elimination method.\r
\n" ); document.write( "\n" ); document.write( "Jill is 27.5 kilometers away from Joe. Both begin to walk toward each other at the same time. Jill walks at 3 kilometers per hour. They meet in 5 hours. How fast is Joe walking?
\n" ); document.write( "

Let Joe's speed be S
\n" );
document.write( "Then we get: 5S + 5(3) = 27.5
\n" );
document.write( "5S + 15 = 27.5
\n" );
document.write( "5S = 12.5
\n" );
document.write( "Joe's speed or  \n" );
document.write( "

\n" );
