${ \footnotesize \color{green}\fcolorbox{white}{m}{ \textsf{ Velocity \: is \: a \: vector \: quantity \: that \: refers \: to}}}$

${ \footnotesize \color{green}\fcolorbox{white}{j}{ \textsf{the \: rate \: at \: which \: an \: object \: changes \: its \: position.}}}$

For more understanding check the picture attached above..

$\tt \large \blue{x = diplacement}$

$\tt \large \blue{ t = change \: in \: time}$
