\n" );
document.write( "Hi, 
\n" );
document.write( "Let x represent time spent traveling to work
\n" );
document.write( "then (2.25hr - x) would be time remaining to travel home
\n" );
document.write( "distance the same both ways.  d = r*t
\n" );
document.write( "22x = 32(2.25hr - x)
\n" );
document.write( "22x = 32*2.25hrh - 32x
\n" );
document.write( "54x = 32*2.25hr
\n" );
document.write( "x = 32*2.25/54 hr
\n" );
document.write( "x = 1 1/3 hr, the time spent traveling to work\r
\n" );
document.write( "\n" );
document.write( "checking our answer
\n" );
document.write( "22*(4/3) = 32*11/12 = 88/3 \n" );
document.write( "

\n" );
