Answer:
By definition, Average speed is the ratio of the "total distance travelled by an object", to the "total time taken by the object" to cover the distance, or,
According to the question,
Total distance travelled by an object
= 18m + 22m + 14m = 54m
Total time taken by the object to cover 54m
= 3s + 3s + 3s = 9s
∴ Average Speed
= 6 m/s (Ans.)
Thus, the average speed of the object will be 6 m/s.
