An automobile travels on a straight road for 25 km at 32 km/h. it then continues in the same direction for another 25 km at 64 km/h. (a) what is the average velocity of the car during this 50 km trip? (assume that it moves in the positive x direction.) (b) what is the average speed? g
the average velocity of the car is (32km/h + 64km/h)/2 = 48km/h in the same direction. the average speed is the same as the average velocity , which is 48km/h.
