Question

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4 °F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation. Complete the steps below to solve the problem.

Part H
Find the water temperature after the submarine’s final dive in decimal form. Show your work.

Answer 1

Elevation = -617.5 feet and the temperature = 61.05 degrees F

Explanation:

The elevation is already -502.5 feet because sea level is 0 and the submarine is 502.5 feet below sea level. Subtracting 115 from that comes out as -617.5 feet.

For the temperature, you have to convert it into decimal form, 63 1/4 equals 63.25. Subtracting 2 1/5 or 2.2 degrees from that comes out as 61.05 degrees F
