Do police officers actually ask the question “Do you know how fast you were going?” - I haven’t gotten a speeding ticket in 20 years, but the one time I did, the officer didn’t ask me that.
I would find it incredibly difficult not to be sarcastic in my response to this question. I imagine my response would be something like:
Approximately, yes, but I don’t know the exact number.
Not admitting any guilt, but admitting that I do know how fast I was going.
