\n" ); document.write( "their rate working together.
\n" ); document.write( "In words:
\n" ); document.write( "(1 route)/(Trent's time) + (1 route)/(Lois's time) = (1 route)/(time working together)
\n" ); document.write( " $\"1%2F30+%2B+1%2F20+=+1%2Fx\"$
\n" ); document.write( "Multiply both sides by $\"60x\"$
\n" ); document.write( " $\"2x+%2B+3x+=+60\"$
\n" ); document.write( " $\"5x+=+60\"$
\n" ); document.write( " $\"x+=+12\"$ minutes \n" ); document.write( "
