7. The figure below 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 f = 0) to f = 20 seconds? (b) What was the average velocity from t = 10 to f = 30 seconds? (c) About how fast was the car traveling at f = 10 seconds? At f = 20? At f = 30? 300- distance (feet ) 200 100 10 20 30 time (seconds)
