Answer

Explanation:

Step1: Define distance and displacement

Distance is total path length, displacement is straight - line distance from start to end with direction.

Step2: Calculate total distance

The dog moves 12 m east and 16 m west. Total distance $d=12 + 16=28$ m.

Step3: Calculate displacement

Let east be positive. Displacement of east - ward motion $d_1 = 12$ m, west - ward motion $d_2=-16$ m. Net displacement $D=d_1 + d_2=12+( - 16)=-4$ m (negative means west direction).

Answer:

Direction Distance (m) Direction Displacement of each motion (m) Displacement of dog (m)
Dog moves east 12 Dog moves east 12 - 4
Dog moves west 16 Dog moves west - 16
Total distance travelled 28
