Good job. Can you do a similar problem with numbers that are not so friendly?
This is my question:
While doing underwater tests in one part of an ocean, a team of scientists noticed that the temperature in degrees celsius was inversely proportional to the depth in kilometres. When the temperature was 6 degrees celsius, the scientists were at a depth of 4km.
i worked out that K= 24
A) To what depth would they have had to go to find the temperature at 2 degrees celsius?
would i do this for the answer:
thanks for any help in advance!
If y and x are inversely proportional, they are related by the equation, y=k/x. (Ther 'inverse' part puts x in the denominator. For direct proportions or 'varyies directly', x would be in the numerator with k.)
Use the given situation to find k. (24 in this problem)
Then in this situation, y=24/x for whatever values of x or y anyone wants to throw at you.
If the 'given' numbers had not been so friendly, we could have still used the same process. Sometimes our brains kind of figure out the answer without telling us how they did it! That's when it's important to know mathematics, so we can slow things down to an understandable pace!
