Answer 1

Average speed = 0.09 meter per second.

Explanation:

Formula used to find the average speed,

Average speed =
`\frac{\text{Total distance covered}}{\text{Time taken}}`

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 =
`(4)/(45)`

= 0.09 m per second

Therefore, average speed is 0.09 m per second.
