It is approximately 3000 km from Portland to Houston. It is approximately 5500 km fromAnchorage, Alaska to Houston. A plane flies in a straight line from Houston to Anchorageand during the flight it passes directly over Portland. Find a vector which describes thedisplacement of the plane.

vector =  -  + 2500

Explanation:

given data

Portland to Houston  = 3000 km

Anchorage, Alaska to Houston = 5500 km

solution

we take here vector displacement from Portland to Houston is =    

and

vector displacement from Houston to Portland is = -

so that here displacement from Houston to  Anchorage, Alaska  is

vector =  -  + 2500
