My math teacher (I'm dropping the course, btw, but not because of this ) gave us a problem that started out like this:
"An airplane is flying at 350 mi/h and one mile high..."
Well, we all know that's a big no-no, seeing as how there's a (287.5mph) 250Kts<-->10,000ft.MSL limit
I scribbled "illegal" and all sortsa stuff on the page, explaining why it's inconceivable, etc., after which we had to turn the paper in.
I wonder what she'll have to say...
Just a little humor
