In 5 minutes, a conveyor belt moves 800 pounds of recyclable aluminum from the delivery truck to a storage area. A smaller belt moves the same quantity of cans the same distance in 8 minutes. If both belts are used, find how long it takes to move the cans to the storage
\n" ); document.write( "---------------
\n" ); document.write( "Larger belt DATA:
\n" ); document.write( "time = 5 min/job ; rate = 1/5 job/min
\n" ); document.write( "------------
\n" ); document.write( "Smaller belt DATA:
\n" ); document.write( "time = 8 min/job ; rate = 1/8 job/min
\n" ); document.write( "-----
\n" ); document.write( "Together DATA:
\n" ); document.write( "time = x min/job ; rate = 1/x job/min
\n" ); document.write( "---------------
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/5 + 1/8 = 1/x
\n" ); document.write( "8x + 5x = 40
\n" ); document.write( "13x = 40
\n" ); document.write( "x = 3.08 minutes = 3 min 4.8 seconds
