Question

A man walks 40 m north, then 70 m east and then 40 m south. What is his displacement from the
starting point?​

Answer 1

Answer:

30 metre is the answer

hope it's help

Answer 2

Man walks 40m north => AB=40m
Man walks 70cm east => BC=70m
Man walks 40m south => CD=40m

Displacement= Shortest distance between the starting point and the ending point = AD
AB=CD=40m
=> BC=AD= 70m
=> AD=70m
=> Displacement = 70m
