And a reasonable interpretation of that is, well, this is when she's walking in one direction and then that's whatever direction we assume is the positive direction, and this is when she's walking the other way. And so she has a positive velocity here and then she has a negative velocity, she has some speed in the other direction, and then she has a positive velocity again. So if you were to take the absolute value of this, if you just cared about the magnitude of the velocity, well, we're talking about speed. But we're not just talking about the absolute value of velocity, we're integrating the absolute value of velocity over time, from time equals zero to time equals 40. So if you integrate speed, if you're saying, okay, for every little amount of time, dt, she has some speed, well, that's gonna give you the distance that she travels. So the distance, remember, is the difference between distance and displacement, is displacement you can think of as the net distance. It takes, if you go back and forth a bunch of times, it's going to add up to the distance, but they're going to net out with respect to each other in displacement.
