There are two dock workers, Alf and Bob. Alf can load 16 tons of steel per day, and Bob can load 20 tons per day. If they each work 8-hour days, how many tons of steel can the two of them load in one hour, assuming they maintain a steady rate?
\n" ); document.write( ".
\n" ); document.write( "Alf:
\n" ); document.write( "16 tons per day
\n" ); document.write( "or
\n" ); document.write( "16 tons per 8 hours
\n" ); document.write( ".
\n" ); document.write( "Bob:
\n" ); document.write( "20 tons per day
\n" ); document.write( "or
\n" ); document.write( "20 tons per 8 hours
\n" ); document.write( ".
\n" ); document.write( "In ONE hour, working together they can load:
\n" ); document.write( "16/8 + 20/8
\n" ); document.write( "= 36/8
\n" ); document.write( "= 4.5 tons \n" ); document.write( "
