\n" ); document.write( "
A more appropriate equation to form in order to get straight to the answer is one of TIME.
\n" );
document.write( "Let distance to Larry's house be D
\n" );
document.write( "Then we get the following TIME equation: \"matrix%281%2C3%2C+D%2F8+%2B+D%2F20%2C+%22=%22%2C+7%29\"
\n" );
document.write( "5D + 2D = 280 ------ Multiplying by LCD, 40
\n" );
document.write( "7D = 280
\n" );
document.write( "Distance to Larry's house, or \"highlight_green%28matrix%281%2C6%2C+D%2C+%22=%22%2C+280%2F7%2C+%22=%22%2C+40%2C+miles%29%29\" \n" );
