Use the table to determine an underestimate of the total distance covered by the car
from the time the driver began to brake at t= 0, until the car stopped.
Considering your answer, which of the following statements can you justify from the
information given above?
The car stopped before reaching the obstacle.
The car did not stop before reaching the obstacle.
