An automobile travels on a straight road for 44 km at 49 km/h. It then continues in the same direction for another 44 km at 98 km/h.
(a) What is the average velocity (in km/h) of the car during this 88 km trip? (Assume that it moves in the positive x direction.)
(b) What is the average speed (in km/h)?
