10 mins.
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.
It would be 117 copies.

You need to convert the minutes and seconds, to minutes. Then you can divide the 165 copies by the number of minutes.
To find out how many copies the machine makes in 5 minutes and 45 seconds, first convert the time to minutes. 5 minutes and 45 seconds is equivalent to 5.75 minutes (since 45 seconds is 0.75 of a minute). Then, multiply the rate of 44 copies per minute by 5.75 minutes: 44 copies/minute × 5.75 minutes = 253 copies. Thus, the machine makes 253 copies in that time.
44 x 4 = 176 copies15 seconds = Quarter (1/4) of a minute1/4 x 44 = 11 copiesTotal copies = 176 + 11 = 187 copies
