A submarine's elevation changes -657 feet over a period of 6 minutes. If the submarine descended at a constant rate, what is the approximate elevation change per minute?
-130 feet
-90 feet
-120 feet
-110 feet

Respuesta :

It would be -110 feet per minute. We find that out by dividing -657 by 6 and getting -109.5, which rounds off to -110.
