# A Body Travels a Distance of 3 Km Towards East, Then 4 Km Towards North and Finally 9 Km Towards East. What is the Resultant Displacement ? - Science

Sum

A body travels a distance of 3 km towards East, then 4 km towards North and finally 9 km towards East.

What is the resultant displacement ?

#### Solution

The body travels a total distance of 12 km east, which means towards the x-axis, on a Cartesian plane. It travels a distance of 4 km in north direction, which means towards y-axis.
Resultant displacement :
sqrt(12^2+4^2)
= sqrt(144 + 16)
= sqrt(160)
= 12.65 km

Concept: Displacement
