yes you are right.
why hour?
if you take 1 mile that is the speed for 1 minute and divide that with the wheel size then why you want go back to 60 miles?
1062 rounds per minute and not hour. of course if you take the real wheel size with the tire than it will be less. but what i wanted to say is why is the AI giving an answer in a range? why not give the correct answer since it is a very simple calculation. i guess because the question was incorrect. giving the wheel size in inches without giving the tire definition is the reason why the AI gave a not precise answer. but what is really fascinating is that the question was how fast rotate a 19" wheel ... and it automatically understood that it doesnot include the tire because when we talk about wheel size it means the wheel without tire but this is how human talk not computers. so this is really impressive.
