A pump is used to fill empty tanks with oil. It takes 27 minuets to fill 6 tanks when the flow rate is 5 litres per second.\r
\n" ); document.write( "\n" ); document.write( "Calculate how long it would take to fill 8 of these tanks when the flow rate is 9 litres per second.
\n" ); document.write( "----------
\n" ); document.write( "Each tank takes (27/6) = 9/2 minutes at 5L/sec
\n" ); document.write( "Tank = (9/2)*60*5 liters = 1350 liters
\n" ); document.write( "-------
\n" ); document.write( "At 9 L/sec:
\n" ); document.write( "1350/9 = 150 sec/tank
\n" ); document.write( "x8 = 1200 seconds = 20 minutes\r
\n" ); document.write( "\n" ); document.write( "
