\n" ); document.write( "

Let normal speed be S
\n" );
document.write( "Then faster speed is: S + 6
\n" );
document.write( "We then get the following TIME equation: 
\n" );
document.write( "270S(2) + S(S + 6) = 270(2)(S + 6) ------- Multiplying by LCD, 2S(S + 6)
\n" );
document.write( "
\n" );
document.write( "(S - 54)(S + 60) = 0
\n" );
document.write( "Normal speed, or  \n" );
