Question

A submersible vessel was

Answer 1

Answer:

5.5 meters above start position.

Step-by-step explanation:

-Let X be the start position.

#Total distance below the start position is calculated as:

$d_{down}=6+5.5\times 7\\\\=44.5\ m$

#Total distance above the start position X:

$d_{up}=50\ m$

#Distance above/below start position is:

$d=X-d_{down}+d_{up}\\\\=X-44.5+50\\\\d=X+5.5\ m$

Hence, The vessel is 5.5 meters above the start position
