Answer:
The plane's displacement is 228.47 km.
Explanation:
It is given that,
Distance covered in east direction is 210 km and distance covered in north direction is 90 km. Let d is the plane's displacement. It is equal to the shortest path covered by the particle.
[tex]d=\sqrt{d_1^2+d_2^2}[/tex]
[tex]d=\sqrt{(210)^2+(90)^2}[/tex]
d = 228.47 km
So, the plane's displacement is 228.47 km. Hence, this is the required solution.
