Answer 1

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\:\:$

$\green{\underline \bold{Given :}}$

$\:\:$

• Total distance covered = $\rm\large{ \frac { 46 } { 3 }}$ km
• Total time taken = $\rm \large{\frac { 23 } { 12 }}$ hr

$\:\:$

$\red{\underline \bold{To \: Find:}}$

$\:\:$

• The speed of runner

$\large{\orange{\underline{\tt{Solution :-}}}}$

$\:\:$

$\underline{\bold{\texttt{We know that}}}$

$\:\:$

$\purple\longrightarrow$ $\sf Speed = \frac { Distance } { Time }$

$\:\:$

$\longmapsto$ $\sf Speed = \frac { 46/3} { 23/12}$

$\:\:$

$\longmapsto$ $\sf Speed = \frac { 46 } { 3 } × \frac { 12 } { 23 }$

$\:\:$

$\longmapsto$ $\sf Speed = 8 km/hr$

$\:\:$

$\underline{\bold{\texttt{Hence speed will be :}}}$

$\red{\bold{8 km/ hr}}$
