A girl walks 100 m at angle of 30° North of West. What is the ratio of the distance travelled by the girl in North to West direction?


Total distance covered by the girl is equal to total displacement = 100m

Angle, straight theta = 30o

Magnitude of the component of displacement along North is, 
straight S subscript 1 equals 100 space sin 30 degree

Magnitude of the component of displacement along West is,space straight S subscript 2 equals 100 space cos space 30 degree

Therefore, the ratio of the distance travelled by the girl in North to West direction is given by,
