我认为第二句是印错的,应该用所有格,即
The clock would strike twelve in twenty minutes' time.
The bird covered the distance in three minutes‘ time.The clock would strike twelve in twenty minutes' time.
The bird covered the distance in three minutes.
两句时间表达，一个所属格，一个不是，有什么区别？请详解
第二句话打错了，麻烦帮忙解释因为time 是名词，所以minutes要用所有格minutes’
