Answer:
Option A is the correct answer.
Explanation:
Let the east point towards positive X-axis and north point towards positive Y-axis.
First walking 1.2 km north, displacement = 1.2 j km
Secondly 1.6 km east, displacement = 1.6 i km
Total displacement = (1.6 i + 1.2 j) km
Magnitude = [tex]\sqrt{1.2^2+1.6^2} = 2 km[/tex]
Angle of resultant with positive X - axis = [tex]tan^{-1}(1.2/1.6)=36.87^0[/tex] = 36.87⁰ east of north.
