A copy machine makes 60 copies per minute. A second copy machine makes 80 copies per minute. The second machine starts making copies 2 minutes after the first machine starts. Both machines stop making copies 8 minutes after the first machine started. Together, the 2 machines made how many copies?
first made = 60*8=480
second made= 80*6=480
together= 960
To find the total number of copies made by the two machines, we need to calculate the number of copies made by each machine and then add them together.
First machine:
Since the first machine makes 60 copies per minute, and it runs for a total of 8 minutes, the first machine makes 60 * 8 = <<60*8=480>>480 copies.
Second machine:
Since the second machine starts making copies 2 minutes after the first machine starts and runs for a total of 8 minutes, the second machine only runs for 8 - 2 = <<8-2=6>>6 minutes.
Since the second machine makes 80 copies per minute, the second machine makes 80 * 6 = <<80*6=480>>480 copies.
Total:
Adding the number of copies made by the first and second machines, the total number of copies made is 480 + 480 = <<480+480=960>>960 copies.
Therefore, the two machines made a total of 960 copies.
To find out how many copies were made by both machines together, we need to determine the time frame during which both machines were operational.
The first machine operates for a total of 8 minutes. Therefore, it makes a total of 60 copies per minute * 8 minutes = 480 copies.
The second machine starts making copies 2 minutes after the first machine starts and stops making copies 8 minutes after the first machine started. So, the second machine operates for a total of 8 minutes - 2 minutes = 6 minutes.
The second machine makes a total of 80 copies per minute * 6 minutes = 480 copies.
Therefore, the total number of copies made by both machines together is 480 copies + 480 copies = 960 copies.
