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