Let both C and D start from point R. C’s path is shown by black and D’s by blue.

C travels 9 km south and reaches S, then takes left turn and reaches point T by travelling 11 km.

Similarly, D travels east for 3 km and reaches Q, then turns south for 5 km and finally stops at point O.

Thus, OT = 9 – 5 = 4 km.

So, D is 4 km to the north of C.
