Next-door neighbors Bob and Jim use hoses from both houses to fill Bob's swimming pool. They know that it takes 24 h using both hoses. They also know that Bob's hose, used alone, takes 50% less time than Jim's hose alone. How much time is required to fill the pool by each hose alone?
\n" ); document.write( ".
\n" ); document.write( "Let x = time (hours) it takes for Jim's hose alone
\n" ); document.write( "then
\n" ); document.write( ".5x = time(hours) it takes for Bob's hose alone
\n" ); document.write( ".
\n" ); document.write( "24(1/x + 1/(.5x)) = 1
\n" ); document.write( "multiply both sides by .5x:
\n" ); document.write( "24(1/x + 1/(.5x)) = .5x
\n" ); document.write( "24(.5 + 1) = .5x
\n" ); document.write( "24(1.5) = .5x
\n" ); document.write( "36 = .5x
\n" ); document.write( "36/.5 = x
\n" ); document.write( "72 hours = x (Jim's hose)
\n" ); document.write( ".
\n" ); document.write( "Bob's hose:
\n" ); document.write( ".5x = .5(72) = 36 hours\r
