\n" ); document.write( "Suppose that one hose can fill a small pool in 4 hours, and a second hose can fill the pool in 3 hours.
\n" ); document.write( "a) Write an equation whose solution gives the time needed for the hoses, working together, to fill the pool.
\n" ); document.write( "b) Solve the equation in part (a) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a.
\n" ); document.write( "

\r\n" );
document.write( "Let time it takes both to fill pool, be T\r\n" );
document.write( "\r\n" );
document.write( "Slower hose fills pool in 4 hours, or  of pool in 1 hour\r\n" );
document.write( "Faster hose fills pool in 3 hours, or  of pool in 1 hour\r\n" );
document.write( "Equation to determine time taken to fill pool, with both hoses working: \r\n" );
document.write( "

b.
\n" ); document.write( "Solve for T. \n" ); document.write( "

\n" );
