I think the anwer would be 125 per copy
Yes
At 1 copy every two seconds, that is 30 copies per minute/ 1000 / 30 = 33 minutes and 15 seconds to complete the entire job.
The copy machine would make 165 copies if it makes 44 copies per minute and 3 minutes and 45 seconds has past.
You need to convert the minutes and seconds, to minutes. Then you can divide the 165 copies by the number of minutes.
3.25 minutes. :)
3 3/7 minutes
It would be 117 copies.

40 copies = 8 minutes 40/40 copies = 8/40 minutes 1 copy = 12seconds 100 copies = 12 x 100 = 1200 seconds = 20 minutes (1200/60) it will take 20 minutes to make 100 copies
207/36 = 5.75 minutes = 5minutes 45seconds
10 mins.
154 coppies. (28 x 5.5 - 28 a minute, and there are five and a half minutes)
