A scuba diver dove from the surface of the ocean to an elevation of -79 9/10 feet at a rate of -18.8 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?

1. descent time: 4.25 min
hover time: 12.75 min
19.125 - 4.25-12.75 = 2.125 min

So, the ascent rate was (-28.9 - (-79.9))ft/2.125min = 24.0 ft/min
