When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London

问题描述:

When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London
与这个句子
for the puma was often observed at one place in the morning and at another place twenty miles away in the evening
为什么一个在miles后有away 而一个没有?

前句后面有south of London,所以不用加away(away,隔开...远),后句away代指another place
