Answer:
At the origin, or (0,0), they were still at the original location.
Then, they traveled 40 meters and stayed there for a long time. We can see this because the distance increased at first and then stayed the same, shown by a straight line. They could've run around and then took a break and sat down.
Then, they traveled very fast to another location, shown by the exponential growth, and stayed there for a while, shown by the straight line. They could've biked somewhere like a restaurant and ate there.
Then, they took one long trip back to the original spot, shown by the straight line and how the distance decreased.
