A Polar Bear who started his walk from the North Pole.
To calculate the total displacement, we can break down the student's movements into net east-west and north-south components. The student walks 3 blocks east, 1 block west (net 2 blocks east), and 2 blocks north, then 2 blocks south (net 0 blocks north). Therefore, the total displacement is 2 blocks east, resulting in a final displacement of 2 blocks east.
To find the total displacement, we need to calculate the net movement in the north-south direction. The child walks 4m south and 5m south, totaling 9m south, and then walks 2m north and 5m north, totaling 7m north. The net displacement is 9m south - 7m north = 2m south. Therefore, the total displacement of the child is 2m south.

If she started from the south pole, then she'll wind up 4 miles from her starting point after this series of maneuvers. If she started on or near the equator, then the final distance is roughly 6.4 miles.
To find the total displacement, we calculate the net movement in the north-south direction. The child walks 4 m south and then 5 m south, totaling 9 m south. They then walk 2 m north and 5 m north, totaling 7 m north. The net displacement is 9 m south - 7 m north = 2 m south.

It's white because these directions can only be in the North Pole; a polar bear! The man lives at the Noth Pole, because that is the only point where the south-west-north walk starts and ends! So the bear is an ice bear!
He started from the North Pole.
Meg's displacement is the straight-line distance from her starting point to her ending point. She walks 5 blocks south and then returns 8 blocks north, resulting in a net movement of 3 blocks north from her original position. Therefore, her displacement is 3 blocks north.
