Let the equal distance travelled is X
Then we know average velocity =Total distance/Total time taken
Here total distance will be= X+X+X
Total Distance=3X
Now time taken by each journey is distance/velocity
The There total time taken is sum of time in all three journey= X/60 +X/20+X/10
Total time =10X/60=X/6
Average Velocity of=3X/(X/6)=18kmph
