The student was heading to school, walked to the west 400 m, then, turned right, walked another 400 m

The student was heading to school, walked to the west 400 m, then, turned right, walked another 400 m, find the path and movements of the student.

These tasks: S1 (the path traveled by the student to the west) = 400 m; S2 (path traveled by the student to the north) = 400 m.

1) Path of the student: S = S1 + S2 = 400 + 400 = 800 m.

2) Moving the student: L = √ (S1 ^ 2 + S2 ^ 2) = √ (400 ^ 2 + 400 ^ 2) = 565.7 m.

Answer: The path of this student to the school was 800 m, while he moved 565.7 m.
