A person moves $30 \mathrm{m}$ north, then $20 \mathrm{m}$ east, then $30\sqrt{2}$ south-west. His displacement from the original position is:

A car moves a distance of $200\mathrm{m}$. It covers the first half of the distance at speed $40\mathrm{km} {\mathrm{h}}^{-1}$ and the second half of distance at speed $\mathrm{v}$. The average speed is $48 \mathrm{km} {\mathrm{h}}^{-1}$. Find the value of $\mathrm{v}$

A particle moves from $A$ to $B$ in a circular path of radius $R$ covering an angle $\theta$ as shown in figure. Find the ratio of distance and magnitude of displacement of the particle.

A student goes from his house to his friend's house with speed $v_1.$ Finding the door of his friends's closed, return back to his own house with the speed $v_2.$ Then the average speed of the student is

A person goes to his office from his home daily at a fixed speed. But today he decided to reduce his speed by $20\%$ as a result he reaches his office $16$ minute late. What's the actual/original time he takes to reach his office daily?
