That means that the magnitude of the velocity is increasing, it's just going in the leftward direction. The magnitude of the velocity is increasing, although it's going in the leftward direction, that means that the speed is increasing. The velocity, this is one of those interesting scenarios, the velocity is decreasing, but the speed, which is what they're asking us in the question, speed is increasing. If you wanted to do it really quick with all of this explanation I gave you, you would say, hey look, what's acceleration? Is it positive or negative? You would evaluate it, say hey, it's negative. You know velocity is decreasing.
