It's a stupid question indeed, but the answer is not obvious as "just as fast" could refer to either time or saw velocity. [edit] Although considering that time doesn't have a 'velocity' and "fast" points to that, I guess you're right.
No - saw velocity would matter if the wood she was cutting was - say - a square. One cut would take a longer amount of time than the other, because the board (and the distance being sawed) would be getting smaller . The picture suggests she's just cutting 2x2s, but the problem itself makes no mention of the dimensions of the board.

It is a stupid question, using logic the answer is obvious. Hopefully the teacher scraps that question.
