and the time required for a stroke is exactly equal to the time interval between strokes
敲钟和间隔时间一样
敲6次+间隔5次 = 11
22/6 = 2
12+11 = 23
23*2 =46

the time required for a stroke is exactly equal to the time interval between strokes 敲钟的时间和两个钟声的间隔时间相同。敲6下，5个间隔+6声钟响，22/(5+6)=2

一开始没理解这一句：the time required for a stroke is exactly equal to the time interval between strokes 敲钟的时间和两个钟声的间隔时间相同。敲6下，5个间隔+6声钟响，22/(5+6)=2

the time required for a stroke is exactly equal to the time interval between strokes 要注意审题

n点敲n下；敲钟时间和间隔时间相同
6点：6下+5间隔=11~22秒

the time required for a stroke is exactly equal to the time interval between strokes 加强审题！

A certain clock marks every hour by striking a number of times equal to the hour, 说明6点会敲6下
and the time required for a stroke is exactly equal to the time interval between strokes. 敲击所需要的时间等于敲击的时间间隔6-1=5
所以22秒内总共走了（5+6=11），所以每走一步花2秒。
敲钟和间隔时间一样，6点时敲6下隔5次，共11次，22秒，每下2秒
12点时，敲12下，隔11次，共23次，46秒
摆坏了，6点的时候应该摆六下花22秒，问12点的时候摆12下应该花几秒。

the time required for a stroke is exactly equal to the time interval between strokes。认真读题。阅读需加强

打击一下所需时间=22/(5+6)=2 5为间隔，6为打击次数
所以12点时需要时间=2*（11+12）=46

所以12点就是敲了12下，间隔是11，每一下花2秒，总共（12+11=23下），23*2=46

楼上说得对。。。

stroke是一个过程：“一来一回”，6点时计时是5.5个“一来一回” 12点时是11.5个“一来一回”
