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. So this right over here is going to give us the total distance, not displacement, that she travels over those 40 minutes. If there was no absolute value sign here, then we'd be talking about the displacement. And so let me write that. So this integral from zero to 40, absolute value v of t, dt, is the total distance, distance she travels, she travels over the 40 minutes. Over the 40, over the 40 minutes. Remember, our unit of time here is in minutes.
