This is familiar, and a solution was given for this same problem at least a couple of times within the last four or five months. \r

\n" ); document.write( "\n" ); document.write( "This is a uniform rates type problem. R for rate, V for volume of water in gallons, T for time in hours, will be related as RT=V. Treat the problem the same way you might treat other uniform rates problems. Make a data table, and assign whatever variables seem fitting.\r
