Answer 2

Answer:

She is travelling in west direction

Step-by-step explanation:

This problem can be solved using vector algebra

East and North are considered positive axes and other are negative.

Given that,

Ths station director drives 15km due west,hence the position vector is -15i

He then takes a left turn,it means he is travelling in south direction.Hence,position vector with respect to previous point is -10j

He then again takes right by 18km,position vector with respect to previous point is -18j

Therefore,She is travelling in west direction
