Step-by-step explanation:

let the initial position of the submarine be -240 m

distance descended = 160 m

=> new position will be

-240m -160 m ....[since the submarine descended]

= -400m

Distance ascended = 390 m

=> final position

= -400m +390 m

= -10m

=> the new position of submarine is 10m below sea level

$\huge \boxed{ \fcolorbox{cyan}{red}{answer : }}$

$\sf{The \: submarine \: is \: situated \: at \: 1240m}$

$\rm{It \: descends 160m}$

$\sf{new \: position \: will \: be}$

$\sf{1240 + 160 m \: from \: sea level}$

$\rm{1400 \: m \: from \: sea \: level.}$

$\sf{it \: moves \: up \: 300 m}$

$\rm{1400 - 300 m}$

$\sf{1100 m \: from \: the \: sea \: level}$
