Question

a person travels 3km towards east and turns towards North and travelled a distance 4km what is the displacement
​

Answer 1

Answer:

As displacement is the shortest distance between initial and final point . Therefore diplacement is

By pythagorous theoram

H^2= P^2+B^2

here P =North=4km

B=east=3km

so , let H = Displacement = d

d^2 = 4^2 + 3^2

d^2 = 16+9

d^2=25

therefore

d= 5km
