You can put this solution on YOUR website!
Let $\"+t+\"$ = Carl's time in minutes
\n" ); document.write( " $\"+%281%2F3%29%2At+\"$ = Thomas's time in minutes
\n" ); document.write( "-------------------------------------
\n" ); document.write( " $\"+t+%2B+%281%2F3%29%2At+=+9%2F2+\"$
\n" ); document.write( "( note that 4.5 = 9/2 )
\n" ); document.write( " $\"+t%2A%28+1+%2B+1%2F3+%29+=+9%2F2+\"$
\n" ); document.write( " $\"+%284%2F3%29%2At+=+9%2F2+\"$
\n" ); document.write( "Multiply both sides by $\"+6+\"$
\n" ); document.write( " $\"+8t+=+27+\"$
\n" ); document.write( " $\"+t+=+27%2F8+\"$
\n" ); document.write( " $\"+t+=+3+%2B+3%2F8+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+%283%2F8%29%2A60+=+3%2A7.5+\"$
\n" ); document.write( " $\"+3%2A7.5+=+22.5+\"$
\n" ); document.write( "It takes Carl 3 min 22.5 sec
\n" ); document.write( "------------------------------
