You find its absolute value which is 11
Answer:
Points that lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are noncollinear points.

First you need to find your True Air Speed (TAS). I used the formula:
where 
is the density at mean sea level at 15°C which is 1.225 kg/m^3 and 
is the density of the air in which the airplane is flying. In this case with the given altitude and air temperature is about: 1.073 kg/m^3.
So TAS is equal to: 123 kt in this case.
To get the time of arrival you need to get your ground speed. For that you need to compensate for the wind speed and direction. With the drift angle you can get your ground speed.
In this case you get ground speed of 115 kt which means to travel 218 nautical miles you need 1 h and 53 min which means you will arrive at: 1135.
The answer is 22.5 you multiply the 7 and the 3
