A 2000L tank containing 550L of water is being filled with water at the rate of
\n" ); document.write( " 75L per minute from a full 1600L tank.
\n" ); document.write( " How long will it be before the two tanks have the same amount of water?
\n" ); document.write( ":
\n" ); document.write( "Let t = time required for the two levels to be equal
\n" ); document.write( ":
\n" ); document.write( "2k tank amt = 1600 tank amt
\n" ); document.write( "75t + 550 = 1600 - 75t
\n" ); document.write( ":
\n" ); document.write( "75t + 75t = 1600 - 550
\n" ); document.write( ":
\n" ); document.write( "150t = 1050
\n" ); document.write( "t = \"1050%2F150\"
\n" ); document.write( "t = 7 hrs
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "Check solution by finding the amt in each
\n" ); document.write( "75(7) + 550 = 1600 - 75(7)
\n" ); document.write( "525 + 550 = 1600 - 525
\n" ); document.write( "1075 = 1075 \n" ); document.write( "
