Hey!
Please find the solution to your query here:
We know that, Time= Distance/ Speed
Therefore, the total time= (X/V) + (2X/2V) + (3X/3V) = 3X/V
And, The total distance traveled = X+ 2X+ 3X= 6X
So, Average speed= Total distance/ Total time
Therefore, average speed= (6X)/ (3X/V) = 2V
Thus, the average speed in 2V.
Hope this answer helps!
