1) Find the hourly rate of each painter.

\n" ); document.write( "If John can paint the house in 6 hours, then he can paint $\"1%2F6\"$ of the house in 1 hour.
\n" ); document.write( "2) Find the hourly rate when working together.
\n" ); document.write( "Together, they can paint $\"1%2F4%2B1%2F6+=+10%2F24\"$ of the house in 1 hour.
\n" ); document.write( "3) Find the time to paint the entire house together.
\n" ); document.write( "They can paint the whole house in $\"24%2F10+=+2.4\"$ hours or 2 hours and 24 minutes. \n" ); document.write( "
