$\underline{\bigstar\:\boldsymbol{According \;to \;the\: given \;Question\; :}}$

⠀⠀

• ${\mathfrak{\pink{Distance,\:s\:=\:ut\:+\:(1\:+\:2)\:at²\:-\:(i)}}}$

⠀⠀

⠀⠀

Substituting the given and known values in the equation (i) we get,

⠀ ⠀⠀ ⠀ ⠀

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{s\:=\:0\:\times\:8\:+\:{\frac{1}{2}}\:\times\:3\:\times\:(8)^{3}}$

⠀ ⠀⠀ ⠀ ⠀

⠀ ⠀⠀ ⠀

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{s\:=\:{\frac{1}{2}}\:\times\:3\:\times\:64}$

⠀ ⠀⠀ ⠀ ⠀

⠀ ⠀⠀ ⠀

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{s\:=\:{\frac{1}{\cancel{2}}}\:\times\:3\:\times\:{\cancel{64}}}$

⠀⠀ ⠀ ⠀

⠀ ⠀⠀ ⠀

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{s\:=\:3\:\times\:32}$

⠀⠀ ⠀ ⠀

⠀ ⠀⠀ ⠀

$\:\:\:\:\:\:\::\:\Longrightarrow\sf\:{s\:=\:96}$

⠀⠀ ⠀ ⠀

⠀ ⠀⠀ ⠀

$\:\:\:\:\:\:\::\:\Longrightarrow\:{\underline{\boxed{\frak{\blue{96}}}}}\:\bigstar$

⠀⠀ ⠀ ⠀

⠀ ⠀⠀ ⠀

$\:\therefore\:{\underline{\sf{The\:distance\:travel\:by\:motorboat\:is\:{\textsf{\textbf{96\:m}}}}}}.$
