Answer:
Average speed = 0.09 meter per second.
Step-by-step explanation:
Formula used to find the average speed,
Average speed = [tex]\frac{\text{Total distance covered}}{\text{Time taken}}[/tex]
From the graph attached,
Total distance covered from t = 0 and t = 45 seconds
= 4 m
Time elapsed during the journey = 45 - 0 = 45 seconds
Average speed = [tex]\frac{4}{45}[/tex]
= 0.09 m per second
Therefore, average speed is 0.09 m per second.
