Oh Goddamn it!! I always hate these word problem ones, "If Jimmy travels 57 mph how long till..."
I usually go with (B) but I see you omitted that possibility (very sneaky of you ). I give up!! By the way, have you checked out the new UAV posting? Looks uber radical.
You mean like "If User A comes to site S, travelling 100 MPH, developing whiplash from all of the career paths he wants to take, asking a thousand questions after doing zero research, how long will it take for the ban hammer to descend?" Something like that?
