. The graph shows the distance of a car from a measuring position located on the edge of a straight road. (a) What was the average velocity of the car from t= 0 to t = 30 seconds? (b) What was the average velocity of the car from t= 10 to t= 30 seconds? (c) About how fast was the car traveling at t=10 seconds? at t=205? at t=305 f) (d) What does the horizontal part of the graph between t= 15 and t= 20 seconds mean? (e) What does the negative velocity at t = 25 represent? distance (feet)
