A person walks 50 m in the north direction and from there he walks 30 m in the west direction.
Now, he/she walks 50 m distance in south direction. Find the distance travelled by the person and his/her displacement.
Find out the average speed and average velocity of person if he/she takes 100 s time to move from initial to final position.

Explanation

Total distance = 130m, displacement =0
Average speed `= 1.3 ms ^(-1),`
Average velocity `= 0.3 ms ^(-1)`
