In a automobile brake test the driver slammed on the brakes to see how long it would take the car to stop completely. See the graph.

About what was the average speed of the car during the first 2 seconds of braking?
A) 41 m/s
B) 50 m/s
C) 72 m/s
D) 80 m/s

PLEASE HELP!!!

a 41

Explanation:  

First, calculate the distance traveled in the first two seconds using the graph. The starting distance is 100 m. The distance at the two second mark is about 18 m. 100 - 18 = 82 m. Next use the speed formula, v = d/t to calculate the average speed: 82m/2s = 41m/s.
