The rate of flow is $\"+50t+\"$ liters/sec
\n" ); document.write( "( liters/sec ) x ( sec ) = liters
\n" ); document.write( "After $\"+t+\"$ seconds, there are $\"+50t%5E2+\"$
\n" ); document.write( "liters in the tank
\n" ); document.write( "After 30 seconds,
\n" ); document.write( " $\"+50t%5E2+=+50%2A30%5E2+\"$
\n" ); document.write( " $\"+50t%5E2+=+45000+\"$
\n" ); document.write( "After 30 sec, there is 45,000 liters in the tank \n" ); document.write( "

\n" );
