Question

A submarine is diving below the surface of the ocean. The depth is 86m. Represent the depth as a negative number. a) -86m b) 86m c) 0m d) 180m

Answer 1

I believe it is “a” -86 m because the surface of the ocean is 0m also known as sea level. The submarine is going down 86 meters below sea level and 0 - 86 is negative 86. Hope this helps and have a good day:)
