Naz is swimming the English Channel from France to England. A few minutes ago, she was swimming in calm waters at a velocity (speed and direction) $\vec{v_1}$ . The direction of $\vec{v_1}$ is due north, and the speed is 8 km/h. Now, however, she has encountered a current. Without changing the way she swims, she is now moving at a velocity $\vec{v_2}$ . The direction of $\vec{v_2}$ is 20° west of north, and the speed is 12 km/h.

(Assume "due east" is 0°, "due north" is 90°, etc.)

What is the speed of the current? (Round to the nearest hundredths)

In what direction is the current flowing? (Round your final answer to the nearest degree, your answer should be between 0° and 360°.)
