Hello, everyone.
I've got a question.
My girl friend and I were supposed to dinner out at 7.
It was 6:50.
And my girl said to me, "We have 10 more minutes.(So why don't you get ready?)"
Then I wonder whether that sentence is correct or not.
I suppose that "We have 10 minutes left."
We had a little argument.
Could you guys let me know which one is correct?
Thanks in advance.

450 on "have five minutes left"

thus both are used in books on a comparable basis.
You have ten more minutes - emphasizes how much longer it will be.
You have ten minutes left - emphasizes how little time is left.
I can't wait for the work day to be over. Ugh. I have 30 more minutes.
You better hurry up on that essay. There are [only] 10 minutes left before you have to hand it in.
I have 10 more minutes
and
I have 10 minutes more -
are they both okay?
You have 10 minutes.
You have 10 minutes left.
You have 10 more minutes.
However, "two minutes more" sounds more natural to me in the following case:
You need to cook it a bit longer.
How much longer?
Cook for two minutes more.
GG, what do you think?
"I only have 10 minutes left",
"I only have 10 more minutes",
or
"I have 10 minutes left until + sub-clause",
"I have 10 more minutes until + sub-clause".
No, I'd say they need to cook at least another two minutes.
No, I'd say that have to cook at least two more minutes.
No, but the timer says it's still two more minutes until they should be done.
Huevos, NONE of these work in isolated situations. You need to have a reason to say them. You wouldn't walk up to someone and say "I have ten more minutes." But if someone says "Excuse me, I think it's my turn to use the computer now" and you point to when you signed in, knowing you have 30-minutes slots, you certainly can say "I have ten more minutes."
EDITED to address the original question.
If I know we have to leave in ten minutes, and my husband is still in his jeans watching TV: Honey, there's only ten minutes left until we have to go. (I hope instead of arguing with her about grammar, you got your butt up and changed your clothes!)
