Question

The distance and displacement respectively covered by a man on reaching point $C$ from point $A$ as shown in the figure is

• A. $5m,7m$
• B. $7m,5m$
• C. $3m,4m$
• D. $4m,3m$

Answer 1

The correct option is B $7m,5m$

Total distance covered by the man is the total path length
$\Rightarrow AB+BC=4+3=7m$
And, total displacement of the man is
$AC=\sqrt{A{B}^2+B{C}^2}=\sqrt{4^2+3^2}=5\text{m}$
