Hi,
\n" ); document.write( "R varies inversely with Time
\n" ); document.write( "R = k/T
\n" ); document.write( "60 = k/8
\n" ); document.write( "k = 480
\n" ); document.write( "R = 480/T
\n" ); document.write( "70 = 480/T
\n" ); document.write( "T70 = 480
\n" ); document.write( "T = 480/70
\n" ); document.write( "T = 6.86 (2 dp)hrs.
\n" ); document.write( "Hope this helps :-)
