Answer:
Step-by-step explanation:
Total distance = 100+ 80+45 m = 225m
Total time = 40+40+20s = 100s
Average speed = total distance /total time
Average speed = 225m/100s
Average speed = 2.25m/s
Hope this helps!!

Answer
Average speed = Total distance/ Total time
Total distance = 100 + 40 + 45 = 225 m
Total time = 40 + 40 + 20 = 100 s
Average speed = 225/100 = 2.25 m/s
