A、60
B、100
C、120
D、200
E、3,000

网考网参考答案：D
网考网解析：
At 3 copies every 4 seconds, the copier will finish the batch in (9,000/3)×4 seconds, or 12,000 seconds. There are 60 seconds in a minute, so 12,000/60=200 minutes. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
