A bicycle traveled 150 meters west from point A to point B. Then it took the same route and came back to point A. It took a total of 2 minutes for the bicycle to return to point A. What is the average speed and average velocity of the bicycle?
average speed is total distance/total time = (150+150)/2 = 150 m/min
average velocity is zero, since the final location is the same as the starting location.
