south20

Explanation:

given,

Girl move 10 m North to drinking fountain          

then she turns to move 30 m south for art room          

to calculate the total displacement = ?

Displacement is the shortest distance between two points.                

Displacement between the two points = 30 - 10                    

                                                                 = 20                          

so, the displacement is 20 in the south direction.

so, the Correct answer is south20                          

they can increase to boost the enonomy.
