First, find the hourly rate of each pipe.
\n" ); document.write( "The first pipe can fill the pool in 10 hours, so it can fill $\"1%2F10\"$ of the pool in 1 hour.
\n" ); document.write( "The second pipe can fill the pool in 6 hours, so it can fill $\"1%2F6\"$ of the pool in 1 hour.
\n" ); document.write( "Together, both pipes can fill $\"1%2F10%2B1%2F6+=+4%2F15\"$ of the pool in 1 hour.
\n" ); document.write( "Therefore, it will take $\"15%2F4+=+highlight%283.75%29\"$ hours for both pipes to fill the pool. \n" ); document.write( "
