$\:$

$\bf{\underline{\underline{Solution}}}$

$\:$

$\tt{As\:we\:know,}$

$\:$

$\bf{\boxed{1000\:m\:=\:1\:km}}$

$\:$

$\tt{so,}$

$\:$

$\bf{4000\:m\:=\:4\:km}$

$\:$

$\tt{According\:to\:Question,}$

$\:$

$\small\tt{A\:Car\:travels\:4\:km\:in\:10\:minutes}$

$\:$

$\small\tt{Converting\:10\:minutes\:in\:hours,}$

$\:$

$\tt{\boxed{1\:hour\:=\:60\:minutes}}$

$\:$

$\tt{so,}$

$\:$

$\tt{Multiply\:both\:by\:6\:}$

$\:$

$\tt{\:4\:km\times\:6\:=\: 10\:min\times\:6}$

$\:$

$\tt{24\:km\:=\: 60\:minutes(1\:hour)}$

Answer 2

$\huge\bold \color{khaki} \mathfrak{Answer}$

Distance travelled by the car = 4000m = 4 km

Time taken = 10 minutes =10/60 hours = 1/6 hours.

$speed = \frac{distance}{time}$

$speed = \frac{4}{ \frac{1}{6} }$

$speed = 4 \times 6 = 24 \: km \: per \: h$

Hope it helps...
