(B) 2 hr. 20 min
(C) 2 hr. 40 min
(D) 6 hr.
(E) 6 hr. 20 min
答案:2hr40min
题目翻译:X 处理 240 个文件要 4 个小时,Y 处理 240 个文件要 8个小时。问 X和 Y 同时处理 240 个文件要多久
思路点拔:先算 X和 Y 的速度,再用 240 除以速度之和即可
题目全解:240/(240/4+240/8)=2hr40min
3、 Circular gears P and Q start rotating atthe same time at constant speeds. Gear P makes 10 revolutions perminute, and gear Q makes 40 revolutions per minute. How many secondsafter the gears start rotating will gear Q have made exactly 6 more revolutionsthan gear P?

(B) 8
(C) 10
(D) 12
(E) 15
答案:12
题目翻译: 齿轮 P 每分钟转 10 圈,Q 每分钟转 40 圈,什么时候 Q 能刚好比 P 多转 6圈
思路点拔:速率:P 每秒转 1/6 圈,Q 每秒转 4/6 圈。设时间为 X 秒,X*Vq-X*Vp=6
题目全解:X*4/6-X*1/6=6 X=12
