A submarine designed to explore the ocean floor is at an elevation of 13,000 feet (below sea level). The submarine ascends to the surface at an average rate
of 650 feet per minute. The elevation e (in feet) of the submarine is given by
the function:
e = 6501 - 13,000
where t is the time (in minutes) since the submarine began to ascend.
