Question

a man moves 4m towards east and 3m towards north calculate the distance and displacement covered by the man

Answer 1

total distance=4+3=7m
displacement=
${x }^{2} = {4}^{2} + {3 }^{2} \\ {x}^{2} = 16 + 9 \\ {x }^{2} = 25 \\ x = 5$
total displacement=5m

Answer 2

total distance=4+3

=7

displacement=x^2 = 4^2 +3^2

x^2 =16+9

x^2 =25

x =5
