Explanation:

Let’s break this down, step by step:

- Start at A. Go 8 km North to B.

- Right turn, 7 km East to C.

- South 12 km to D.

- Left, 13 km East to E.

- Left again, 6 km North to F.

- Go 10 km West to G.

- Left, 16 km South to H.

- Turn left, 16 km East to I.

- Left again, 8 km North to J.

Now, C’s position (if A is (0,0)):

- B: (0,8)

- C: (7,8)

Now, sum up all the later movements from C to J.

If you sketch it out or do the math—net movements from C to J are: +13+16-10=19 km East, and -12+6-16+8=-14 km (i.e., 14 km South).

So, C to J: 19 km East, 14 km South.

Distance = v(19² + 14²) = v(361+196) = v557 ˜ 23.6 km

Direction: From C, J is to the South-East.

Here’s what that means for your options:

- 23.6 km North-west

- 23 km South-east

- 23.6 km South-east

- 23 km North-west

- 23.1 km North-west

That’s the breakdown: option 3, 23.6 km South-east, is spot on.
