Before watching the videos, think about and answer these questions to the best of your ability. Your answer will always be recorded as correct, regardless of your answer choice.

A car speeds up as it drives away from a traffic light. The cars GPS unit records its distance from the light in the table below:

Table 1: Time and Distance
Time (seconds) Distance (meters)
0 0
1 1
2 3
3 6
4 10
5 15
6 21
7 27
Compute an approximation of the cars speed at the 5-second mark. .
Is the value you computed:
Equal to the cars speed at the 5-second mark An underestimate of the cars speed at the 5-second mark An overestimate of the cars speed at the 5-second mark Neither an underestimate nor an overestimate You cant tell without having more information
How could you improve your approximation of the cars speed at the 5-second mark?
You dont need to make an improvement because the speed you calculated is the cars speed at the 5-second mark Use a different pair of points from the table to compute the speed Use two pairs of points from the table to compute two speeds, and then average these speeds Use a larger interval of time (e.g., if you originally used a 1-second time interval, a 2-second time interval would improve your approximation) Use a smaller interval of time (which would require additional information)
