Average seed is total distance divided by total time taken so the ans is 6 m/s

Answer 2

Hello there!

Average Speed of an object is the Total Distance covered by the object divided by the Total Time taken to cover the said distance.

Total Distance = 18 + 18 = 36m
Total Time Taken = 4 + 2 = 6s

Hence Average Speed = 36/6 = 6 m/s
