You can put this solution on YOUR website!
H varies inversely as t is written H $\"alpha\"$ 1/t. We convert this to an equation by putting in a constant - call it k, so:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"H+=+k%2Ft\"$ . We now need to fix this value of k ie find its value. So we need to be given H and t...which we are in the question, amazing coincidence :-)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "12 = k/3
\n" ); document.write( "--> k = 12*3
\n" ); document.write( "k = 36\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the equation is H = 36/t\r
\n" ); document.write( "
