Given:-

• $\sf \: Speed ,s = 54km/h$
• $\sf \: Time ,t = 10min$

To Find:-

• $\sf \: Distance \: covered \: by \: car \: ,d \:$

Solution:-

$\sf \pmb {According \: to \: the \: Question}$

$\sf \: we \: have \: to \: calculate \: the \: distance \: covered \: by \: car .</p><p>$

$\sf \: Firstly \: we \: change \: the \: \: speed \: into \: m/s \: by \: multiplying \: 5/18 .$

$\sf:\implies \: s = 54×5/18$

$\sf:\implies \: s = 3×5$

$\sf:⟹ s = 15m/s$

Now, converting the time into second

⠀⠀⠀⠀⠀⠀⠀⠀

$\sf \: :⟹ 1min = 60 s$

$\sf: \implies 10min = 60×10 = 600s$

$\sf \: Calculating \: the \: distance \: covered \: by \: car .$

$\sf \: d = st \\ \sf \: where,$

$\: \: \: \: \: \: \: \: \: \: \sf \: d \: denote \: distance \\ \: \: \: \: \: \: \sf \: s \: denote \: speed \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf t \: denote \: time \: taken$

Substitute the value we get

$\sf:⟹ d = 15×600$

$\sf \: :⟹ d = 9000m$

$\sf \: :⟹ d = 9000/1000 km$

⠀⠀⠀⠀⠀⠀⠀

$\sf \: :⟹ d = 9km$

• $\sf \: Hence, \: the \: distance \: covered \: by \: the \: car \: is \: 9 \: kilometres.$
