$\:$

Given :—

$\:$

• A car covers a distance of 5 km in 10 min

$\:$

To Find :—

$\:$

• The speed of the car in

1. km/min
2. m/sec

$\:$

Solution :—

$\:$

Formula used

$\:$

$\begin{gathered}{ \underline{ \green { \boxed{ \bf{speed = \frac{distance}{time} }}}}} \end{gathered}$

$\:$

★ In km/min

$\qquad : \implies \sf{speed = \dfrac{5}{10} }$

$\:$

$\qquad : \implies \sf{speed = \cancel \dfrac{5}{10} }$

$\:$

$\qquad : \implies \sf{speed = 2km/min }$

$\:$

★ In m/s.

$\:$

5 km to m :

$\:$

$\rightarrow 5 \times 1000$

$\:$

$\rightarrow \sf 5000 \: m$

$\:$

10 min to sec :

$\:$

$\rightarrow 10 \times 60$

$\:$

$\rightarrow \sf{600 \: sec}$

$\:$

$\:$

$\qquad : \implies \sf{speed = \dfrac{distance}{time} }$

$\:$

$\qquad : \implies \sf{speed = \dfrac{50 \: \cancel{00}}{6 \: \cancel{00}} }$

$\:$

$\qquad : \implies \sf{speed = \cancel \dfrac{50}{6} }$

$\:$

$\qquad : \implies \sf{speed = 8.3 m/sec }$
