Let normal speed be S
\n" );
document.write( "Then normal time = 
\n" );
document.write( "On this day, her speed was: S – 10, and she took  hours to get to her destination
\n" );
document.write( "We then get: ________
\n" );
document.write( "150(2)(S – 10) = 150(2S) – S(S – 10) --------- Multiplying by LCD, 2S(S – 10)
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "(S - 60)(S + 50) = 0
\n" );
document.write( "Normal speed, or S =  mph          OR            S  = - 50 (ignore)
\n" );
document.write( "Time taken to complete trip: , or , or  hours \n" );
