If Emily jogs 3 laps to warm up at 5 mph then runs three more at 7 mph what is true about her average speed and average velocity?

Emily's average speed can be calculated by taking the total distance she covers and dividing it by the total time taken. Since she jogs 3 laps at 5 mph and 3 laps at 7 mph, her average speed will be between these two speeds, leaning closer to the faster speed due to more distance covered at that rate. However, her average velocity will depend on her displacement; if she returns to the starting point after completing all laps, her average velocity will be zero, as velocity considers direction.
