Explanation:
Find the motion diagram attached for the illustration:
Distance is the length of path traveled from the start to the finish. In measuring distance, we wall through the path from start to the finishing point. Distance is a scalar magnitude that has magnitude but no direction.
Displacement is distance that is taken between the start and finishing point. It is a vector quantity that has magnitude and measures direction.
To find the distance;
Distance = 5km + 7km = 12km
Displacement:
Using pythagoras theorem;
Displacement = √7² + 5² = 8.6km
Direction:
sin(bearing ) =
bearing = arcSin 0.5814 = 035.6°
Displacement is 8.6km in a direction 035.6°
