Let outbound speed be S
\n" );
document.write( "Then return speed = 2S
\n" );
document.write( "We then get the following TIME equation: \"matrix%281%2C3%2C+5%2C+%22=%22%2C+500%2FS+%2B+500%2F%282S%29%29\"
\n" );
document.write( "\"matrix%281%2C3%2C+1%2C+%22=%22%2C+100%2FS+%2B+100%2F%282S%29%29\" ------ Reducing fractions by factoring out numerator GCF, 5
\n" );
document.write( "2S = 200 + 100 ------ Multiplying by LCD, 2S
\n" );
document.write( "Return speed or \"highlight_green%28matrix%281%2C4%2C+2S%2C+%22=%22%2C+300%2C+mph%29%29\"
