A submarine started at sea level and was 400 meters below sea level in 10 minutes. Which statement correctly explains the submar
ine’s rate of movement? A. Since = 40, you find that the submarine ascended at a rate of 40 meters per minute. B. Since = –40, you find that the submarine ascended at a rate of 40 meters per minute. C. Since = 40, you find that the submarine descended at a rate of 40 meters per minute. D. Since = –40, you find that the submarine descended at a rate of 40 meters per minute.
I would say D.) Because the rate is 40 and you are indeed descending. Between this answer and C.) I'd choose this one because it has the negative sign in front of the 40 to communicate that the sub is indeed descending.
