$\huge{\pink{\underline{\underline{\bf{\star\;SoluTion:}}}}}$

Given,

Speed of Man = 7.8 m/s

Distance To Cover = 9km

_________________________

$\boxed{\sf{1\;km = 1000\; meters}}$

→ 9km = 9×1000m

→ 9000 Meters

__________________________

Time Taken = ?

$\boxed{\sf{Time = \frac{Distance}{Speed}}}$

$→\;{\bf{Time = \frac{9000}{7.5}}}$

$→\;{\bf{Time = 1200sec}}$

_______________________

$\boxed{\sf{1\; Second = \frac{1}{60}\;minutes}}$

→ $\frac{1200}{60}$

➝ $20\; minutes$
