A. 5m/s
B. 2.5m/s
C. 10m/s
D. 20m/s

See picture above

Answer 1

Answer:a five meters hope this helps ;)

Step-by-step explanation:

Answer 2

A. 5 m/s

Step-by-step explanation:

From the graph, for the first 2 seconds, the graph is a straight line meaning that the slope is a constant.

Average speed of an object is the rate of change of position. Here, the position of the object changes from 0 m to 10 m for a time interval of 2 seconds.

The change in position (
`\Delta x`) and time interval (
`\Delta t`) are given as:

`\Delta x=10-0=10\ m\\\Delta t=2-0=2\ s`

Therefore, the average speed (
`s_(avg)`) is given as the ratio of the total change in position and the time interval for the change.

`s_(avg)=(\Delta x)/(\Delta t)=(10-0)/(2-0)=(10)/(2)=5\ m/s`

Hence, the average speed is 5 m/s.
