English: which is correct 'Twenty more minutes' or 'Twenty minutes more'?
A friend of mine who works at an English teaching school here in Russia was rebuked by her boss for saying ‘I need twenty more minutes, please’, which, she was told, was incorrect because one should say ‘twenty minutes more’. Is her boss right or are both ways of saying it correct (as I’ve always believed)?
