Question 7 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 4 Celsius,
What is the water temperature at a depth of 800 meters?
Find the constant of variation k.
ka
Using the k from above find the water temperature in degrees Celsius at a depth of 800 meters.
Celsius. (If needed, round answer to 2 decimal places.)
