if you walk 400m around the track. what will be your distance traveled? what will be your displacement

Distance: 400 meters

Displacement: zero vector, (0,0)

Explanation:

Distance is a scalar measuring the ground covered during a motion: 400m in this case.

Displacement is the difference between the beginning and end location vectors of an object. Since the track is a closed loop and the walk ends at the same location where it started, the difference in (x, y) coordinates is (0,0), i. e. a zero vector.
