\n" );
document.write( "Keiko bicycles 8km/h faster than Javier. 
\n" );
document.write( "Let x and (x+8) represent Javier's and Keiko's speeds respectively
\n" );
document.write( "Question states*** Note: D = rt or D/r = t
\n" );
document.write( "In the same time it takes Javier to bicycle 30 km, Keiko can bicycle 54 km.
\n" );
document.write( "  Cross Multiplying to solve
\n" );
document.write( "    54x = 30x + 240
\n" );
document.write( "      24x = 240
\n" );
document.write( "        x = 240/24 =10kmph, Javier's speed.  Keiko's speed is 18kmph \n" );
document.write( "

\n" );
