An airplane flies 800 km east and 600 km north. What is the total displacement (with approximate direction)? What is the total distance traveled?

Total displacement is found using pythagorean theorem

d = sqrt( 800^2 + 600^2) = 1000 km

Direction is given by Tan = opp/adj = 600/800 arctan (600/800) = 36 .9 degrees

For displacement, I was told to subtract the final position - the initial position.

Doing that I got

-200km North

Not sure who told you that, but it is incorrect.....sorry

Hypothetical example: IF you move 800 east and then 400 west THEN your displacement would be 800 - 400 = 400 This ONLY works with displacements along a LINE.
