After one hour in flight, an airplane is located 100 miles north and 200 miles west of the airport. What direction is the plane traveling? Round your answer to the nearest degree.

Dec 16th, 2014

Assuming the angle of the flying plane to the west is A

Then tan(A)=100/200=1/2

A=tan(-1)(1/2)=27 degree

So the plane is flying 27 degree to the west towards the north.
