A hiker walks due East for a distance of 6 km
solniwko [45]

Resultant displacement between the base camp and the cave will be 7.211 km

Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

Her resultant displacement can be calculated using Pythagoras theorem

H^{2} = P^{2} + B^{2}

     = 4^{2} + 6^{2}

     = 52

H = \sqrt{52} = 7.211 km
