Two 3D printers are turned on at 8:00 AM if one can produce 48 items
and the other can produce 41 items each other, at what time will they produce a total of 712 items.
~~~~~~~~~~~~~~~~~
In = = 8 hours.
They will complete the job at 4:00 PM that day.
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
