This is a rate problem
\n" ); document.write( "Terry's rate of painting is ( 1 house)/(4 hrs)
\n" ); document.write( "Nissi's rate of painting is (1 house)/(6 hrs)
\n" ); document.write( "Let \"t\" = the time it takes them to paint the
\n" ); document.write( "house working together
\n" ); document.write( "Just add their rates to get their rate working together
\n" ); document.write( "\"+1%2F4+%2B+1%2F6+=+1%2Ft\"
\n" ); document.write( "Multiply both sides by \"12t\"
\n" ); document.write( "\"+3t+%2B+2t+=+12+\"
\n" ); document.write( "\"5t+=+12+\"
\n" ); document.write( "\"+t+=+2.4+\"
\n" ); document.write( "Their rate working together is (1 house)/(2.4 hrs)
\n" ); document.write( "To convert \".4\" hrs to minutes:
\n" ); document.write( "\".4\" hrs x \"60%2F1\" min/hr = \"24\" min
\n" ); document.write( "It takes them 2 hours and 24 minutes working together
\n" ); document.write( "
\n" );
