Patrice can do the job in 10 hours, so she can do 1/10 of the job in 1 hour.
\n" ); document.write( "Patrice and April together can do the job in 6 hours, so they can do 1/6 of the job in 1 hour.\r
\n" ); document.write( "\n" ); document.write( "Therefore: April can do in 1 hour what (Patrice + April) - Patrice can do in 1 hour.\r
\n" ); document.write( "\n" ); document.write( "(P + A) - P = 1/6 - 1/10 = 5/30 - 3/30 = 2/30 = 1/15 of the job in 1 hour.\r
\n" ); document.write( "\n" ); document.write( "So, April can do 1/15 of the job in 1 hour, so it will take her (15/1) hours to do the entire job.\r
\n" ); document.write( "\n" ); document.write( "April will take 15 hours to paint the four rooms.
\n" ); document.write( "
