The speedboat B is cruising to the north at 75 mi/hr when it encounters an eastward current of speed but does not change its heading (relative to the water). Determine the subsequent velocity of the boat relative to the wind and express your result as a magnitude and compass direction. The current affects the motion of the boat; the southwesterly wind of speed does not.
