A scuba diver dove from the surface of the ocean to an elevation of −89 9 10 feet at a rate of −20 feet per minute. After spending 12.75 minutes at that elevation, the diver ascended to an elevation of −28 9 10 feet. The total time for the dive so far was 19 1 8 minutes. What was the rate of change in the diver's elevation during the ascent? Round your answer to the nearest hundredth.

Solve the equation 3x2 + 19x + 9 = 0 to the nearest tenth.
