Two 3D printers are turned on at 8:00 AM if one can produce 48 items and the
other can produce 41 items each hour, at what time will they produce a total
of 712 items.

The printing rate of the first 3D printer is 48 items/hour, so in x hours it
will print 48x items.

The printing rate of the first 3D printer is 41 items/hour, so in x hours it
will print 41x items.

So in x hours, it will print 48x+41x or 89x items. For this to equal 712
items,

      89x = 712
        x = 712/89
        x = 8 hours.  So 8 hours from 8:00 AM is 4:00 PM
