3-50.

The four places where events take place are the places where the slope changes:

1) The spot where the graph flattens out momentarily

2) The long horizontal section of the graph

3) Where the slope is negative for a short time

4) Where the slope is negative for a long time

moving forward → positive slope

moving backward → negative slope

stopping → __________

If velocity is slope of the distance graph... so speeding would mean steep slope. Be mindful that speeding could mean steep-and-positive or steep-and-negative.
