A scientist uses a submarine to study ocean life.
*She begins at sea level, which is an elevation of 0 feet.
*She descends for 91 seconds at a speed of 2.2 feet per second.
*She then ascends for 32 seconds at a speed of 0.7 feet per second.
At this point, what is her elevation, in feet?

evaluate , using distance = time x rate
91(-2.2) + 32(.7) = .... ft , your answer will be negative, showing it is below
sea level.
