Faster than a cab but Metro is much more likely to be your delay than the Acela. Also keep in mind that the Metro station is on the outer edge of the cemetery. Depending on where you're going it may take 15-20 mins to walk.
If it's an absolute can't-miss, there's a plethora of hotels in Rosslyn, Court House, and Pentagon City that would be a safer bet.
