You are on a hike in the mountains. You have 4.76 km left to go before your next campsite.
The sun will set in 5.95 h.
What average speed must you walk to get
to camp at sunset?
Answer in units of km/h.

the answer would be   dignified - apex

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
