Person moving Velocity question

[TT0]

Hello, for the diagram above, if a person moves straight then runs in a circle around the starting point will the velocity stay constant? Since velocity is displacement/time, the displacement will be constant.

Thanks

Velocity is a vector, meaning it has both a magnitude (speed) and direction. When you change either direction or speed, you change velocity.

I see so if the person was on the most right then his velocity would be "displacement/time right, is this correct?

Basically, yes.
