Naz is swimming the English Channel from France to England. A few minutes ago, she was swimming in calm waters at a velocity (sp

eed 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°.)

All help is appreciated, thank you! Please note: I will not accept links to answers nor answers that are incomplete, inappropriate, and irrelevant to the topic. Any answers like those WILL be reported and moderators will deal with them correspondingly. Once again, thank you for your help!

Use addition to show how to find 16-9
Daniel [21]
It would be 9 + x =16 
To solve it, subtract 9 from both sides of the equal sign
So (9+x)-9=16-9
Which is x=7, so the answer is 7.
