The average length of time that 3 lawn service mowers operate on a given day is 930 minutes. None of the mowers operates for less than 900 minutes. What is the greatest possible length of time any of the mowers operates?
\n" ); document.write( "-------------
\n" ); document.write( "If one is the max, it occurs when the other 2 are a minimum
\n" ); document.write( "The total is 3*930 = 2790 minutes
\n" ); document.write( "900 + 900 + Max = 2790
\n" ); document.write( "Max = 990 minutes
\n" ); document.write( "
\n" ); document.write( "
