Physics

 A body moves with a velocity of 36 km $${ h }^{ -1 }$$ . What is the value of the velocity in m $${ s }^{ -1 }$$ ?


SOLUTION
Velocity $$=36\ km/hr$$

Since $$1\ km=10^3\ m$$

and $$1\ hr=3600\ sec$$

$$\therefore \ V=36\dfrac {km}{hr} =36\times \dfrac {1000}{3600}$$

$$=36\times \dfrac {5}{18}$$

$$=10\ m/s$$
