Sketching Kinematic Graphs for a Person's Movement from a Reference Point

[koolkidx45]

A person starts 50m [N] of a reference point then walks until hs is 50m of the reference point. The person then jogs until he is 50m [N] of the ref. point. The person then runs until he is at the ref. point.

How do i sketch a velocity vs time graph and an acceleration vs time graph for this scenario.

Any help is appreciated. Visual images would be nice

Thanks!

Put the north-south axis on the vertical (where the y-axis usually is), and the time axis to the right. Now sketch the person's position as a function of time. For the part where the person is running, will the slope be greater or less than when they are walking?
