Araon is nervous about his ap biology quiz. While studying he paces around the room. over a 120 second period, he moves 3m forward, 2.5 back, 7m forward, 10m back and 2m forward what was the average speed

Answer :

average speed = total distance travelled / total time taken
total distance = 3 + 2.5 + 7 + 10 + 2 = 24.5
total time = 120 seconds
therefore 24.5/120 is
0.2m per second.
