Aboat travels from a port and moves 12 miles north and then moves 5 miles east. what is the present distance of the boat from the port?

What helped me find the answer if I am correct would be that I drew a number line to represent the distance the boat is moving from the port. The first thing I did was I drew an arrow pointing to the right all the was to the number 12 and then I drew another arrow pointing to the left to show that the boat moved 5 miles to the east and the the question asked now how many miles is the boat from the port so the answer would be 7 miles. P.s. Sorry this is s long.

The answer to your question is the last one
