grammaticality - Word order: "10 minutes more" or "10 more minutes"?

• I'm still packing my clothes. I'll need 10 minutes more.


• I'm still packing my clothes. I'll need 10 more minutes.

Are both grammatically correct?

Answer

They're both correct. But "I need 10 more minutes" is probably more common. (There's no reason to make it progressive or conditional. The need is in the present.)
