An Aircraft's Displacement Calculation

What is the magnitude of an aircraft's displacement after flying 800km due East and then 600km due North?

Magnitude of its displacement = 1,000 km

Explanation:

Given: Distance towards east = 800 km, Distance towards north = 600 km

Find: Magnitude of its displacement

Computation:

Magnitude of its displacement = √800² + 600²

Magnitude of its displacement = √640000 + 360000

Magnitude of its displacement = √10000000

Magnitude of its displacement = 1,000 km
