Find the ground speed of an airplane with air speed of 480km/hr and heading due east if a wind blowing south has a velocity of 40km/hr. I did this: plane: wind: And added them together to get and then used Pythagorean theorem to get a speed of about 481.664. Is this correct?

Find the ground speed of an airplane with air speed of 480km/hr and heading due east if a wind blowing south has a velocity of 40km/hr.

I did this:
plane: <480, 0>
wind: <0, -40>

And added them together to get <480, -40> and then used Pythagorean theorem to get a speed of about 481.664. Is this correct?
