A ship at A is to sail to C, 56km north and 258km east of A. After sailing N25°10’E for 120mi to P, the ship is headed toward C. Find the distance of P from C and the required course to mean C.

Use the same method I showed you in your post before this.

The exception here is that you know the final destination to be the ordered pair (258,56)

After converting (120 , N25°10' E) subtract that vector from (258,56)

I am assuming your distance of 120 mi was meant to be 120 km.

BTW, for an alternate solution look at

where the same question was posted and answered before.

Are you the same person, by the exact typing error and use of "mean" for C I assume you are.
