Assuming that the question is as follows: - 
 
An object travels 18 metre in 4 seconds and next 18 metre in two seconds calculate average speed of the object.
 
Solution: - 
Average speed = Total distance travelled/Total time taken 
 
Here, total distance = 18 m + 18 m = 36 m 
Total time taken = 4 s+ 2 s = 6 s 
Thus, 
average speed = 36/6 = 6 m/s 
The average speed of the object is 6 m/s
