Lets say we represent the amount of time she could ski.
So it would be x = the amount of time she skis
And 5x would represent how long it took her to climb
and she took 9 minutes to climb.
So what we would do first is put it in a equation like this
x + 5x = 9
Now we have 6x = 9
Divide 9 by 6x, and we get x = 15
So multiply 1.5 by 5 and the answer would be 7.5
Hopefully this helped. :)
The answer to ur question is 15
and 
are the <em>farthest</em> from the origin and 
is the <em>closest</em> from the origin.
Let be a curve of the form 
. The distance with respect to origin is found by using the following Pythagorean identity:
(1)
Where 
is the square distance function.
We can modify (1) as following:
![r = [27-3\cdot (y-2)^{2}]+y^{2}](https://tex.z-dn.net/?f=r%20%3D%20%5B27-3%5Ccdot%20%28y-2%29%5E%7B2%7D%5D%2By%5E%7B2%7D)
(1b)
Now we apply the First and second derivative tests to determine the minimum and maximum distances from the origin:
First derivative test
Second derivative test
The y-component represents a maximum.
Now we graph the function with the ressource of a graphing tool, we find the following points:
Farthest points: , .
Closest points: .
and are the <em>farthest</em> from the origin and is the <em>closest</em> from the origin.
