Rational Equations

Question

The water temperature in the ocean varies inversely with the depth of the water. The deeper a person dives, the colder the water becomes. At a depth of 1,100 meters, the water temperature is 3º Celsius. What is the water temperature at a depth of 900 meters?

Find the constant of proportionality k.
k = ____________ (If needed, round answer to 2 decimal places.)

Using the k from above find the water temperature in degrees Celsius at a depth of 900 meters.
The water temperature will be__________ º Celsius. (If needed, round answer to 2 decimal places.)

Answer 1

Here ya go:

 

T = k/D

3 = k/1100

3300 = k


T = 3300/D

T = 3300/900 = 33/9 = 11/3 = 3 and 2/3 degrees

Well besides the temperature issue with the formula, the diver can only

go so deep anyways before the water pressure crushes him or her and

he or she drowns.
