Question

A submarine was at a depth of 255 meters below sea level.

The submarine rose 65 m. Then it dove 25 m. Write an equation
with integers to express the situation. Then find the new depth of the
submarine.

Answer 1

Explanation:

If the submarine was at the 255 m below sea level and he rose 65m, his new depth will be 255-65=190 m

than he dove 25 m

190+25=215m

an equation can be 255-65+25=215
