Read the scenario.
A lizard is at an initial position of 2 m and walks to a position of 10 m in 4 s.
What is the lizard’s average velocity?
Responses
-3 m/s
-3 m/s
2.5 m/s
2.5 m/s
3 m/s
3 m/s
2 m/s
To find the lizard's average velocity, we need to divide the change in position by the change in time.
The change in position is 10 m - 2 m = 8 m.
The change in time is 4 s.
Therefore, the average velocity is 8 m / 4 s = 2 m/s.
So the correct response is 2 m/s.
To calculate the average velocity of the lizard, we need to divide the displacement by the time taken.
Displacement = final position - initial position = 10 m - 2 m = 8 m
Time taken = 4 s
Average velocity = Displacement / Time taken = 8 m / 4 s = 2 m/s
Therefore, the lizard's average velocity is 2 m/s.
