\n" ); document.write( "Here is yet another simple way to solve the problem.

\n" ); document.write( "As tutor @ikleyn says after showing you three simple methods, you will be a better student if you know several ways of solving a problem. The more tools you have in your tool bag, the more you will be able to accomplish.

\n" ); document.write( "The hot water faucet fills the bathtub 4 times as fast as the cold water faucet.
\n" ); document.write( "That means in filling the tub together, the hot water faucet does 4/5 of the work.
\n" ); document.write( "Then, since the hot water faucet fills 4/5 of the tub in 3 minutes, the amount of time it would require to fill the tub alone is 5/4 of 3 minutes:

\n" ); document.write( "\"%285%2F4%29%2A3+=+15%2F4\" or 3 3/4 minutes, or 3 minutes 45 seconds
