 \huge \sf \underline \red{Answer : }

 \sf \underline \purple{ \therefore \: Distance \:= \: 9.6km}

 \huge \sf \underline \blue{Solution : }

\sf {Given}\begin{cases}&\sf{speed = 48 \: km} \\ \\ &\sf{Time = 12 \: minutes}\end{cases}

 \sf \underline{so \: ATQ}

 \sf{ \: time = 12 \: minutes =  \dfrac{12}{60}hr}

 \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \: \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   = \sf\normalsize{\sf{\cancel{  \dfrac{12}{60}}}}

\:  \:  \:  \:  \:  \:  \:  \:  \: \: \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    \sf{ =  \frac{2}{10}hr}

 \sf \underline{Let \: distance \: be \: x}

 \sf \underline{we \: know \: that : }

  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \sf{ \boxed{ \underline{ \underline{ \red{ \sf{Speed=  \dfrac{Distance}{Time} \: }}}}}}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \sf \star \: {speed = 48}

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \sf \star \: {distance= x}

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \sf \star \: {time =  \dfrac{2}{10} }

 \sf \underline{putting \: the \: values}

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \sf{ \boxed{ \underline{ \underline{ \red{ \sf{Speed=  \dfrac{Distance}{Time} \: }}}}}}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \sf \implies{48 =  \dfrac{x}{ \dfrac{2}{10} }}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \sf \implies{48 =  \dfrac{10x}{2}}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \sf \implies{48 \times 2 = 10x}

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \sf \implies{96 = 10x}

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \sf \implies{x =  \dfrac{96}{10} }

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \normalsize\implies{ \sf \:x = \sf{\cancel{\dfrac{96}{10}}}}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \sf \implies{x = 9.6 }

 \sf \underline{ \therefore \: Distance = 9.6km}
