问题 If a copier makes 3 copies every 4 seconds, then continues at this rate, how many minutes will it take to make 9,000 copies?

选项 A、60
B、100
C、120
D、200
E、3,000

答案 D

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.
