If Brenda can clean the house in 2 hours and Kenny can clean the house in 3.5 hours, how long will it take them to clean the house if they work together?\r
\n" ); document.write( "\n" ); document.write( "Brenda Data:
\n" ); document.write( " time = 2 hrs; rate= (1/2)job/hr.
\n" ); document.write( "Kenny Data:
\n" ); document.write( " time = (7/2) hrs; rate = (2/7)job/hr.
\n" ); document.write( "Together Data
\n" ); document.write( " time = x hrs; rate = (1/x)job/hr.
\n" ); document.write( "EQUATION:
\n" ); document.write( " rate + rate = rate
\n" ); document.write( " 1/2 + 2/7 = 1/x
\n" ); document.write( "Multiply both sides by 14x to get:
\n" ); document.write( " 7x + 4x = 14
\n" ); document.write( " 11x = 14
\n" ); document.write( " x= 14/11 = 1.273 hrs = 1 hr 17 minutes\r
