Inlet ‘1’ and ‘2’ together can fill a tank in 18 hours. Inlet ‘2’ can fill the tank on its own in 24 hours. In how many hours can inlet ‘1’ alone fill the tank?
\n" ); document.write( ".
\n" ); document.write( "Let x = time (hours) for inlet 1 alone
\n" ); document.write( "then
\n" ); document.write( "18(1/x + 1/24) = 1
\n" ); document.write( "multiplying both sides by 24x:
\n" ); document.write( "18(24 + x) = 24x
\n" ); document.write( "432 + 18x = 24x
\n" ); document.write( "432 = 6x
\n" ); document.write( "72 hours = x
