Final answer:
The average speed is 0.36 m/s.
Step-by-step explanation:
The average speed can be calculated by dividing the total distance traveled by the total time taken. In this case, the total distance traveled is 0.90m and the total time taken is 2.5s. Therefore, the average speed is:
Average Speed = Total Distance / Total Time
Average Speed = 0.90m / 2.5s = 0.36 m/s
So, the average speed is 0.36 m/s to the nearest hundredth.
