Thanks for your prompt reply, Gillnetter!
So "a half hour " means 30 minutes.
I also have a vague memory that I saw "half an hour" before.
Does it mean 90 minutes?
I am always confused by it.
May I have your help?
Thanks a lot!
Hello, teachers:
"You won't have been there much more than a half hour."
Does "a half hour" mean 90 minutes?
Thanks for your confirmation.

"A half hour" and "half an hour" both mean 30 minutes. "An hour and a half" is 90 minutes.
I got it.Thanks a lot!
A half hour = AmE
Half an hour = BrE
Nitpick: its "a half-hour," with a hyphen, or "half an hour," with no hyphen. But yes, both mean 30 minutes, while "an hour and a half" means 90 minutes. You didn't ask, but 150 minutes would be "two and a half hours," not "two hours and a half," as one of my students wrote recently.
