You can put this solution on YOUR website!
Let the time be x
\n" ); document.write( "Equation:
\n" ); document.write( "40x+30(x+2)=270
\n" ); document.write( "40x+30x+60=270
\n" ); document.write( "70x=210
\n" ); document.write( "x=3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, it will take them 3 hours to meet.
