Answer:
She is 5 km from his initial position and in SOUTH EAST direction.
Step-by-step explanation:
Refer the attached figure
A lady walks 8 km towards east i.e. AB = 8 km
Then She walks 3 km towards south i.e. BC = 3 km
Then She walks 4 km towards west i.e. CD =4 km
Now we are supposed to find how far is she from his initial position i.e.AD
ED = BC = 3 km
EB = DC = 4 km
AB - EB = AE
8 km - 4 km = AE
4 km = AE
In ΔAED
Hence she is 5 km from his initial position and in SOUTH EAST direction.
