Gazelle's equation:
\n" ); document.write( "\"+d+=+47t+\"
\n" ); document.write( "Cheetah's equation:
\n" ); document.write( "\"+d+%2B+1+=+65t+\"
\n" ); document.write( "----------------
\n" ); document.write( "\"+d+\" is the distance in miles that the gazelle
\n" ); document.write( "goes when the cheetah catches it
\n" ); document.write( "\"+d+%2B+1+\" is the distance the cheetah goes
\n" ); document.write( "when it catches the gazelle, so the
\n" ); document.write( "right expression is \"+65t+\"
\n" ); document.write( "---------------
\n" ); document.write( "By substitution:
\n" ); document.write( "\"+47t+%2B+1+=+65t+\"
\n" ); document.write( "\"+18t+=+1+\"
\n" ); document.write( "\"+t+=+1%2F18+\"
\n" ); document.write( "The cheetah runs for 1/18 of an hour
\n" ); document.write( "\"+60%2F18+=+3.333+\" min
\n" ); document.write( "\"+.333%2A60+=+20+\"
\n" ); document.write( "The cheetah runs for 3 min 20 sec
\n" ); document.write( " \r
\n" ); document.write( "
