Answer:
15km
Step-by-step explanation:
9km north and 12km east to find the distance from starting point we will use Pythagoras theoram = it will form a triangle
we will name the sides A B C
to find distance=BC
9km = AB
12KM=AC
bc square= absquare+ac square
=81+144
bc square=225
bc=15 because square root of 225 is 15
