An automobile travels on a straight road for 40 km at 30kph. It then continues in the same direction for another 40 km at 60 kph. (a) What is the average velocity of the car during this 80 km trip? (Assume that it moves in the positive x direction.) (b) What is the average speed? (c) Graph x versus t and indicate how the average velocity is found on the graph.
