Question

A submarine started at 750 m below sea level it rose 50 m/h over a four hour. Which expression represents a new position of the summary in relation to sea level

Answer 1

–750 + 4(50)

Explanation:

I believe this is the correct answer.

below sea level is indecated as a negitive so it would be -750

Then rising would be positive so it would be 50*4

so –750 + 4(50) should be the correct answer

Answer 2

It is now at 700m below sea level
