Because its DiffEq, I'm assuming these were intended to be accelerations rather than velocities. So, he starts walking away and then picks up into a sprint. She starts at a crawl and advances to a steady walk.
But I bet the person writing the prompt (or the app translating the question) fumbled the notation for s^2, so now (hopefully) the entire class is going to fail this question and get it curved out.

Agreed. But even then, who the hell walks away from a point with linear acceleration? That's really hard to picture.
I mean, its a math problem at its heart, not an engineering problem.
