So in orange, I have v of t, but if I were to do the absolute value of v of t, I'll do that in magenta. So the absolute value of that is that. Absolute value of that is that. Absolute value of that is that. Absolute value of negative 220 is going to be positive 220. So we saw here, when t is equal to 24, v of t is negative 220. She's running in the opposite direction, or jogging in the other direction, but we're going to take the absolute value of that.
