document.write( "Question 1146094: There are two machines that produce aluminum cans. The newer machine can produce 7200 cans in 180 minutes. It takes the older machine 360 minutes to produce that many cans. If the two machines work together, how long will it take them to produce 7200 cans? \n" ); document.write( "
