the copy machine in the math workroom can make a copy of a document every 3 seconds. how many copies can I make in 17 minutes?

Respuesta :

The printer can print 340 documents in 17 minutes. There is a total of 60 seconds per minute. 17*60= 1020 seconds. You can only print a copy of a document every 3 seconds. 1020/3= 340
