The speed : 2222.2 cm/s
Further explanation
Velocity has magnitude and direction
Can be formulated :
[tex]\tt \boxed{\bold{v=\dfrac{d}{t}}}[/tex]
v= velocity, m/s
d=distance=m
t=time,s
convert from km/h to cm/s :
[tex]\tt =80\dfrac{km}{h}\times \dfrac{10^5~cm}{1~km}\times \dfrac{1~h}{3600~s}\\\\=2222.2~\dfrac{cm}{s}[/tex]
