Two runners travel along the same straight path. They start at the same time, and they end at the same time, but at the halfway mark, they have different instantaneous velocities. Is it possible for them to have the same average velocity for the trip?

Question

They wouldn't, right? Because instantaneous velocity is just the midpoint of the average velocity and if they start and end at the same time, then shouldn't their instantenous velocity be at the same time? Unless one sped up and then slowed down while another slowed down and sped up? But shouldn't their velocities remain constant?

of course their average velocities are the same avg velocity = totaldistance / total time

Thanks. I guess I was just overthinking it.
