$\"+x%2F40%2Bx%2F30=1\"$
\n" ); document.write( " $\"+%283x%29%2F120%2B%284x%29%2F120=1\"$
\n" ); document.write( " $\"+%283x%2B4x%29%2F120=1\"$
\n" ); document.write( " $\"+%287x%29%2F120=1\"$ cross multiply
\n" ); document.write( " $\"+7x=120\"$ divide each side by 7
\n" ); document.write( " $\"+x=120%2F7=17.14=17\"$ so it would take about 17 minutes \n" ); document.write( "
