Answer:
I will end up at the same place I started
Step-by-step explanation:
On a map if I travel 600 mi due south from Washington D.C. it will be a straight line down. After that the west direction will be a straight line towards the left which will be 600 mi. Then going north from this point will be straight line upwards which will be 600 mi. Then going east will be a straight line towards the right for 600 mi reaching the point of origin.
Hence, I will reach Washington D.C.
