Answer:
Displacement= 12.65 km S 18.44°W
Step-by-step explanation:
Justin rides on hist 12 km south.
He changes location and goes 4 km west.
The displacement from his current location = X
X²= 12²+4²
X²= 144+16
X²= 160
X= √160
X= 4√10
X= 12.649 km
X= 12.65 km
His total distance covered=12+4
His total distance covered= 16 km
Tan ^-1 12/4= angle
71.56° = angle
90-71.56= 18.44°
Displacement= 12.65 km S 18.44°W
