A jogger runs 224 meters eastward, then 156 meters westward, then 84 meters eastward, and finally 248 meters westward.

What is the distance, magnitude and the direction of the displacement?

Explanation:

Distance is the length of the path traveled.  Displacement is the difference between the final position and initial position.

Distance = 224 m + 156 m + 84 m + 248 m = 712 m

Displacement = 224 m − 156 m + 84 m − 248 m = -96 m

Displacement = 96 m westward

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
