Answer:
A. 3 m/s
Explanation:
The average speed is the total distance covered over total time taken.
The total distance covered is 6 meters.
The total time taken is 2 seconds.
The average speed in meters per seconds is
![Average \: \: speed = (total \: distance)/(total \: \: time)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/q72r06l5u3j5g5ud6zaaw9nujuew7dkq4f.png)
![Average \: \: speed = (6)/(2) = 3 {ms}^( - 1)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vi9ud2mis03mtwlvuh24qqr6twlyzc8b6v.png)
Therefore the average speed is 3m/s
The correct answer is A.
