Answer:
The resultant displacement is 45 m in east.
(C) is correct option.
Explanation:
Given that,
Julianna walks 45 meters East, 45 meters South, and 45 meters North.
The direction of AB in east, it is in positive, BC in south, it is in negative and CB in north, it is in positive.
We need to calculate the resultant displacement
Using formula of resultant displacement
[tex]D=AB-BC+CB[/tex]
Put the value in to the formula
[tex]D=45-45+45[/tex]
[tex]D = 45\ m[/tex]
Hence, The resultant displacement is 45 m in east.
