两个半小时是two and a half hours?two hours and a half?hour后有s吗

两个半小时是two and a half hours?two hours and a half?hour后有s吗 请问“两个半小时”是“two and a half hour”还是“tow and a half hours”? one hour and a half 是一个半小时 两半小时是不是 two hours and a half? two hours and a half two and a half hours' walk可不可以说two hours and a half's walk two hours and half a hour 2个半小时 这种表达对吗 2个半小时用英语说应该是two and half an hours,还是two and a half hours? 一个半小时 英语：是one and a half hour 还是 one and a half hours 两个半小时除了可以说two and a half hours 还可以说什么 two and a half hours与a half and two hours哪一个对? "two and a half hours" 有什么相同的句子? 一个半小时英文怎么说到底是one and a half hour还是one and a half hours 哪个正确,
