Because your taking a educated guess on what will happened if the track member drinks the energy drink
No, because the distance-time would show a constant velocity but the velocity-time graph shows an increasing velocity.
Well, it would be fossilization. <- If I spelled it correctly.
Answer:
Average speed = 1.2 m/s
Average velocity = 0.4 m/s
Explanation:
Average speed = total distance/total time
Average speed = (40 + 20)/(40 + 10)
Average speed = 60/50
Average speed = 1.2 m/s
Average velocity = displacement/time
Now, she ran 40 m south and ran 20 m back north which is in the direction of where she began the journey.
Thus;
Displacement = 40 - 20 = 20 m
Average velocity = 20/50 = 0.4 m/s
