Answer:

645 feet.

Step-by-step explanation:

I. Given plus is rise up and minus is goes down, when the submarine is underwater so

{submarine} = -645

{rise up} = +100 -645

           = -545

{go down} = -100 - 545

                 = -645 or 645 feet underwater

That makes -645 is the interger represents the charge of submarine position.

Hope that help :)
